Andrew Daugherty, 48, was found shot to death on April 28, 2012, at his mother’s home on the 5200 block of Lexington Avenue in North St. Louis. Responding officers discovered his body with fatal gunshot wounds and the St. Louis Metropolitan Police Department opened a homicide investigation. Initial accounts did not name a suspect or give a clear motive.

Daugherty had been the center of a high-profile case decades earlier. In 1979, at 16, he was arrested, convicted of first-degree murder in the beating and suffocation of 79-year-old Reverend Edward Filipiak at the Shrine of St. Joseph, and sentenced to life. He served about 15 years and was paroled in the mid-1990s, returning to live in St. Louis until his 2012 death.

Few details about arrests or the shooter were released immediately after the killing. Does anyone have information about who might have targeted Daugherty or about activity near Lexington Avenue that night?
