A teenager wanted for investigation of the drive-by shooting death of a 5-year-old girl killed himself after police surrounded his apartment, authorities said Saturday.

Rance Benson, 18, shot himself in the head in the inner-city apartment late Friday, said police Detective Jim Tiampo.Benson and a 17-year-old boy had been sought in the Nov. 10 slaying of Ashley Johnson, who was shot to death while she played hopscotch at a birthday party, Tiampo said. The name of the 17-year-old, who was arrested Thursday, was not released because of his age.
