DOMINGOS AND EDWARDS - PISTOL OR RIFLE ?

6/16/2024

 
Picture
​It was reported that "detectives found 15 empty .22 brass casings toward the mouth of the creek approximately 20 feet from the ocean", ​fired from an "assassin about 25 yards away (75 feet), who then moved in", suggesting that these 15 casings were grouped at this location. Sheriff Webster stated "We know that the maximum number of bullets contained in a 22-caliber rifle tube-type magazine is 15 and a clip magazine is nine". Therefore, it is reasonable to conclude that there was a shooter standing by the mouth of the creek in a fixed position (75 feet from where the couple eventually fell), who fired 15 quick-fire shots from a rifle with a tube magazine. These were likely the shots fired at the couple from distance, before the murderer moved in close to complete his attack. If 20 shots were fired that afternoon, it would mean 5 shots were delivered while the killer was standing over Robert and Linda. If ​26 shots were fired, it would mean 11 at close range. Below I have placed this information into the topography.

POSITION OF BULLET CASINGS BASED ON SEVERAL NEWSPAPER REPORTS
Picture
From everything we have read, it has been concluded that the murderer of Robert Domingos and Linda Edwards dragged each body approximately 30 feet to a nearby shack (a total of 60 feet), which gives the impression that both Robert and Linda fell to the ground in roughly the same position before being moved. Therefore, if we go with the widespread claim that the couple simultaneously ran for their lives along this 75 feet path away from the shooter, how likely is it that both would succumb to their injuries in almost the same spot? Did one likely stop to help the other? Or is it more reasonable to conclude they were walking away from an individual and both were shot close to the position they fell (95 feet from the ocean). For example, they may have been walking 50 to 60 feet away from the killer when he opened fire, which disabled them to some extent, before they both managed (under continued gunfire) to muster another 15 to 25 feet before collapsing. Would this scenario place the couple closer together, at a location 30 feet from the shack?

The grouping of 15 casings 20 feet from the ocean appears to suggest that the killer fired 15 continuous shots from a rifle with a tube magazine, before walking toward the couple and reloading as he went. Had he been in possession of a .22 caliber handgun like Lake Herman Road, one might expect the shooter to have ejected 10 casings 20 feet from the ocean at this fixed position, reloading his weapon as he moved northwards and resuming firing as he approached the couple (or when he arrived at the stricken pair). It is unlikely he would have fired 10 shots from a handgun, stood still and reloaded, fired another 5 shots from the same position, and then moved forward. If the location of the casings is accurate, everything points to a killer who used a rifle on June 4th 1963. 

This excerpt from Zodiac Killer Facts is typical of the consensus theory behind the Gaviota murders: "No one knows the precise timing and sequence of the events that followed, but, at some point, a man apparently confronted Robert and Linda. He was armed with a .22 caliber weapon, possibly a rifle. Investigators believed that the man produced pre-cut lengths of rope and ordered Linda to tie-up Robert’s hands. After that, the man may have tried to bind Linda’s hands, but, Robert somehow freed himself and fought back long enough for the couple to run away. The man apparently shot both Robert and Linda in the back and they fell to the ground together"..This sequence of events is highly unlikely because it requires us to believe that an assailant pointing a gun at Linda and ordering her to tie up Robert, got close enough to the couple for Robert to tackle the perpetrator. After the struggle with the man, rather than stay in the fight and make sure the man was disarmed before they left, it is theorised that Robert and Linda ran away into 75 feet of open space with a man positioned behind them armed with a rifle (who had already threatened them with it). This man then fired 15 shots at the fleeing couple who both managed to run 75 feet each before they fell, despite the fact it is claimed he fired 20 shots in total and struck the couple 19 or 20 times. This would mean that the killer, a very good marksman, managed to hit Robert and Linda at least 14 times as they ran a combined total of 150 feet away from his position (with Linda struck once in the right leg). Is it a realistic proposition that both would travel this distance before succumbing to their injuries? Betty Lou Jensen managed to run just 28 feet from the rear of the Rambler after being hit 5 times on December 20th 1968 with the same ammunition. There is something about the Gaviota Beach story that just doesn't ring true.

Very well tackled and articulated subject matter, Richard.

Certainly a case that needs a lot of ''space'' to digest.

From what you have conveyed, I think the perpetrator's main weapon of intent (maybe only as a threat, initially) was a rifle.

Linda's bathing costume was cut, exposing her breasts ? Given the wholeness of the physical crime - this looks like a tokenistic gesture by the perpetrator, once he had finished with the couple. To leave a false clue that there might have been a sexual-related motive. When there actually wasn't any.

But, it does seem to indicate, that the perpetrator was armed with a knife, also. A hunter's knife ? This, coupled with a rifle, and shooting at ''live'' targets (Linda & Robert), suggests the perpetrator was a hunter, by recreation at the least. Possibly ex-military also.

From what I have read in the past, Robert & Linda knew this spot, and now saw it as a ''lovers' hideaway'' when opportunities presented.

The crime does seem ''territorially'' motivated - that then, as you have intimated, got out of hand. The perpetrator had effectively, claimed the spot for himself (possibly for night-time accommodation ?). He may have left items behind, in order to hint to Robert & Linda - that they were using his patch. But, they just hadn't, or didn't want to receive the message.

The perpetrator then resorting to drastic measures of threatening them - which also came with anger.

Of course, there remains many possibilities Rubislaw. I suspect this crime was sexually motivated, otherwise just leave once you have killed two individuals, rather than waste valuable time dragging two bodies anywhere from 30 to 50 feet each. This desire superseded any fear of being detected during this period. There is no definitive proof that the killer attempted to burn the shack, so in absence of any unrealistic attempt to burn the shack, we have one noticeable feature - the cut bathing suit. The person who brought the ammo to the shack clearly had reason to do so, such as hunting small animals and birds, or possibly humans. Two incidents happened either side of these murders on July 2nd, with people being shot at in one incident. Whether they traced the position of the sniper on July 2nd and retrieved any casings for comparison is anybody's guess. This would have told us whether the Domingos & Edwards murders were an isolated act of rage or a pattern of a mentally disturbed individual who was just targetting random people for no other reason than a misguided sense of fun. Whatever the case, that amount of ammo equates to "time spent" in that location, not a fleeting visit. I just found another article that read "Blood spots and .22 caliber rounds were found in a creek bottom about 50 feet from the shack. Spots were found at intervals of from three to fifteen feet along the creek edge". This would place these casings approximately 20 feet shy of where it is believed the bodies of Robert and Linda were dragged to the shack from. So did the killer open fire on the couple as he approached them from this distance? Or is it possible he dragged them 50 feet to the shack. Regardless, we seemingly have two sets of casings, 75 feet from where they fell and close to where they fell. I have seen no reports of any casings found between these two points. So, if these reports are relatively accurate, he wasn't chasing and firing at the couple.

Also, if the shooter fired 15 shots at the couple as they fled from the beach, then an equal spread of hits would have been 7 on Robert and 7 on Linda (assuming one miss). How do both manage to make it 75 feet if the shooter opened fire almost immediately. If the spread was 8 & 6, or 9 & 5, it's even less likely that one of them would make that distance. Everything points to a killer who began firing when they were already a fair distance away. This of course would lend to more inaccuracy in targetting and therefore could support the 26 or 27 shots scenario.

Fascinating extra information, Richard.

We're probably agreed that the perpetrator had spent some time at that spot - days, even a couple of weeks. Probably, Linda's & Robert's killing was the perpetrator's ''final act''. He would have to ''get the hell out of there'' for good, now. And, I think he was, technically ''homeless'' - living out of his motorcar. Maybe securing casual work within just a few miles of the spot. That would have been my line of enquiry, initially, anyway. Local small businesses, like gas stations.

Richard

Very possible Rubislaw that he was itinerant in nature. It renders geographic profiling pretty much obsolete in this case because the least effort principle is negated. But I think we are on the same page that this individual was undoubtedly familiar with this location, making a noticeable absence of an individual subsequent to the crime something somebody may have noticed. However, in absence of locating the weapon, all we are left with today is blood found on some rocks near the railway tracks that could be anyone's. And I sincerely doubt remains in evidence today, as per usual.

Richard
6/17/2024 02:15:12 am

What we really need are the autopsy reports. These would answer so many questions. I highly doubt that every shot but one, struck the couple in the back.

Rubislaw32 link
6/17/2024 02:36:40 am

Yes - I think you are more genned up on the actual slayings, than me. I'm just not committed enough, at present.

The shack to me, in relation to the killings, represents concealment of their bodies. To buy the perpetrator time in getting as far away from the area as possible. If it had been an altercation that got out of hand - or indeed firing at the couple as soon as he arrived in situ - it was still ''rash actions'', and his self-survival instincts would have kicked-in thereafter. To just get away from the carnage.

Rubislaw32 link
6/17/2024 03:04:13 am

Certainly something to consider, Richard:

By arriving and appearing at the shore line, was this a deliberate act to deny the couple access to the water, as a means of escape. Linda was wearing her bathing costume. He may have already witnessed them swimming, and had assessed them to be comfortable in water.

Was his intention just to scare them away (?) giving them the opportunity to leave in the direction of where their car was ?

But, as you have mentioned also, there is a chance that he was not mentally stable. He may have already decided he was going to kill them.

Rubislaw32 link
6/17/2024 08:48:50 am

I suppose now, a further scenario that presents itself ? His positioning close to the shore line indicating he elected to approach them first, when they were swimming, and separated from basic belongings at the shack, like Robert's car keys (?), for instance.

If Robert got the better of a physical altercation, when the couple came out of the water, Robert still didn't think to throw his rifle away - like in the water. A conundrum of possibilities (?) on the spur of the moment.

Rubislaw32 link
6/17/2024 09:49:04 am

Yes, the autopsy might be of equal value to assess the nature of Robert's physical injuries, beyond bullets. If Robert was hit with something harder than a fist, it could indicate a rifle butt. That, Robert got ''too close and personal'', and he hit Robert with his rifle. Then Linda steps in to remonstrate, and the couple indicate they are leaving.

The perpetrator's anger builds up again, as the couple make their way back to the shack, and decides to take pot-shots at them.

Saw a american gun youtuber dug into this case and added impot apparently the ammo is a very weak ammo/bullet. so he they survived/took so many bullets ,.. he commented on this with the car murders....
he was on a podcast with a assui who didnt know much about bullet streght/impact

Richard

Not the most powerful ammo no, but 8 or 9 shots into somebody's back while running away by a shooter who is supposedly 95-100% accurate, makes me doubt the likelihood of either Robert or Linda making 75 feet in distance. Even if it didn't kill you quickly it would debilitate you.

Howdy! Another great article here Richard. Kind of awful to discuss but the morgue photos show that several of Linda’s fingers were blown off of her left hand. I’m no gun expert but with a .22 that would have to be very close range I would think and obviously with her hands free in a defensive position.

Horrible photos Drew, puts a horrible reality into true crime that we often shove to the back of our minds. I truly hope Mr. Averitt gets the answers he has desperately searched for. When I looked at the slim pickings in the newspapers it described some casings 50 feet from the shack. If these were the only ones in this area and the bodies were 30 feet from the shack (even allowing for casing ejection), this would suggest that when the killer moved in close he still fired from more than point blank (around 15-25 feet). However, I am relying on slim pickings. The autopsy photos of Linda and Robert are difficult to interpret. Did their bodies have powder marks?

Richard
6/17/2024 04:11:50 pm

I've updated the diagram in the article Drew. I know it's based on newspaper accounts, but it's the best information we've got. It suggests that the killer fired 15 shots 20 feet in from the ocean, before approaching the couple somewhere close to the blue circle and fired the remaining 5, or possibly 11/12 shots.

Drew

Hi Richard, a few bits of info here in no particular order… I’ve gone through many of JB Averitt’s comments but have yet to come across any mention of gun shot residue. A few things I had forgotten were the towel (owned by one of the victims) covering Linda’s face. Another is the mention of a fistfight Robert had days before the murders (apparently this unnamed person was cleared). It sounds like they have 3/8 inch rope in evidence (not that that explains Linda’s defensive wounds or that they were cut in advance of the day). The reported sniper activity in vicinity in weekend prior combined with absence of tire impressions near the Domingos car and the abundance of cheap ammo (and practise level weapon) make it seem like the killer (singular in JBA’s assessment - mine too these days because of the drag marks, two people would likely carry the bodies…) had been there for some time before the kids arrived, likely for target practice.

Richard

Dr. John Blanchard said there were some powder burns on the bodies and estimated that the couple had been dead for 24 hours at the time of their discovery.
