On September 2nd 1976 at about 6:30pm, Kathleen Keohane (17) was spending some time with her fiance Mike Warren at Carrows Restaurant, where he was working as a dishwasher. She had decided to leave the restaurant for a walk to pass some time, planning to meet him back at the restaurant when his shift ended at 10:00pm. She never made it back and was found face down and fully clothed in shallow water under the Upper Truckee River Bridge 12 hours later.(6:30am). Investigators determined that Kathleen Keohane had been struck in the back of the head several times with a heavy blunt instrument, causing a massive skull fracture.
When she left the restaurant she had told her fiance she was going to head to the "Y", which is the shape formed on a map by the intersecting Highway 50 and Interstate 89 at Tahoe Valley. Kathleen would have traveled along Lake Tahoe Boulevard. This was a 4.5 mile journey, so would have taken her at least 3 hours to walk there and return back to Carrows Restaurant at 9:30pm. Had she completed the outward journey, she would have been about 4,000 feet from where her body was found.
The location of her body under the Upper Truckee River Bridge was 3,900 feet from where Carol Andersen's body was found on Sundown Trail in 1979. Both murdered teenagers were found fully clothed. The Sahara Tahoe Hotel, where both Brynn Rainey and Donna Lass worked, was 3,400 feet from Carrows Restaurant. Donna Lass would have walked along Lake Tahoe Boulevard in 1970 had she decided to walk to her 3893 Pioneer Trail Road apartments from the Sahara Tahoe Hotel in the early morning hours of September 6th. Brynn Rainey would have walked along Lake Tahoe Boulevard in 1977 had she decided to walk to the Sahara Tahoe Hotel from the Bittercreek Saloon shortly before her shift on July 25th. Carol Andersen would have joined Lake Tahoe Boulevard on June 30th 1979 had she decided to walk to her Lower Kingsbury residence after leaving a party on Regina Road. Kathleen Keohane would have been walking along Lake Tahoe Boulevard after leaving Carrows Restaurant. Four females, four murders, one road.
