On the morning of May 14, 1986, at about 6:10 a.m., Ed LeDuc, an unarmed Sharp Hospital security officer, was checking the corporate office building at 3131 Berger Avenue when he appears to have interrupted a commercial burglary in progress. LeDuc was attacked and struck to death with an antique rifle taken from one of the offices.

The burglary pattern in 1985–1986 involved groups breaking windows with rocks and stealing office equipment such as IBM Selectric typewriters. Several typewriters were found stacked just inside a door leading to the parking lot at the Berger Avenue building; the suspects had fled the scene.

Who remembers activity in that business park that spring of 1986 or saw vehicles or people around 3131 Berger Avenue early on May 14?
