Authorities say Philip Trenary, who also served as the CEO of the Greater Memphis Chamber, was killed in a shooting that happened about 8 p.m. Thursday in the 500 block of South Front Street in downtown Memphis.

Memphis Mayor Jim Strickland confirmed Trenary’s death.

Strickland tells The Commercial Appeal ( “… My thoughts are with his family and Chamber colleagues.”

Police described the suspect as a black male, wearing a blue shirt and driving a white four-door Ford F150. An investigation is ongoing.

The Commercial Appeal reports that Trenary founded Lone Star Airlines in Oklahoma in 1984 and came to Memphis in 1997 to run a regional airline that morphed into Pinnacle.
