View Larger Map

The Boulder Coroner's Office has identified those involved in a double-homicide/suicide that took place at 2403 Bluff Street, an address visible above (if you have trouble seeing the image, click "View Larger Map"). They are Elizabeth Schwarzenbach-Dileo, 63; Philip F. Dileo, 61; and the couple's son, Philip Christopher Dileo, 23. Police believe that the senior Philip Dileo was the shooter, and note that he was employed as a Boulder Police officer for two brief stretches during the first half of the 1970s. He'd threatened his family with violence in the past. The bodies were found yesterday morning, but they'd likely been there since the previous day -- and a suicide note, complete with information about funeral arrangements, argues that the killings were premeditated.

Police release details in double homicide-suicide

Boulder police are releasing additional details surrounding the deaths of three family members in the 2400 block of Bluff Street. The bodies were discovered at about 11:30 a.m. on Tuesday, May 26, after a housekeeper flagged down an officer to say she had found a female who was either deceased or in need of medical attention.

The coroner's office has identified the individuals as Elizabeth Schwarzenbach-Dileo, 63; Philip F. Dileo, 61; and the couple's son, Philip Christopher Dileo, 23. All three had been shot. Based on evidence at the scene, investigators believe the suspect is Philip F. Dileo.

Police recovered two guns. A Ruger .22 semi-automatic handgun with a silencer was found in the kitchen in the area of Elizabeth Schwarzenbach-Dileo's body. A second gun, a .357 Magnum revolver was located upstairs near Philip F. Dileo's body. Investigators are still working on tracing the ownership of these guns.

Based on witness accounts, investigators believe the shootings occurred sometime in the late morning on Monday, May 25. A note, spelling out Philip F. Dileo's desires for funeral arrangements, was located in a spare bedroom.

Police have had contact with this family previously. In 2005, Elizabeth Schwarzenbach-Dileo came to the police department to talk with an officer about the legality of purchasing a gun because her husband had made threats against her. There are indications that he previously threatened their son, as well.

In addition, the police department has checked its records and is confirming that Philip F. Dileo worked as a Boulder police officer for a brief period of time. Employment records show he was employed from October 1972 to June 1973 and again from October 1975 to November 1975. The records indicate he was terminated as a result of multiple violations of department policy.
