The suspect in Wednesday's triple murder in Gardendale committed suicide just hours after the killings, authorities said. Kenneth Lever, 52, shot himself, after getting pulled over in Pensacola, Fla., according to Escambia County Sheriff David Morgan. Lever's car was spotted by an off-duty deputy who pursued the vehicle. Other patrol cars converged, and trapped Lever in a parking lot, where he shot himself, the sheriff said. Police say Lever gunned down his ex-wife, 50-year old Dana Lever, her sister 65-year old Bonnie Foshee and that woman's husband 69-year old Don Foshee, both of Fultondale. The killings, at the Peachtree Crossings community, were believed to be related to domestic dispute. Walker said the couple's daughter witnessed the killings, but was not targeted. "You've got an 11-year old girl, who's lost her whole world," Walker said. "Tonight, just say a prayer for her." The police chief said the girl was heading to a graduation ceremony with her aunt and uncle, when Lever appeared, and began shooting outside the home. Walker expressed appreciation to law enforcement agencies that assisted, including the Jefferson County sheriff's office, the FBI, ATF, and the U.S. Marshals.
