MILWAUKEE (AP) -

Two days after George Zimmerman was acquitted of killing Trayvon Martin in Florida, a trial begins for a white Milwaukee man accused of fatally shooting a black teen whom he suspected of theft.

Seventy-six-year-old John Henry Spooner is charged with first-degree intentional homicide in the 2012 death of his neighbor. Spooner confronted 13-year-old Darius Simmons on the sidewalk and accused him of stealing his guns. Darius denied stealing anything, and prosecutors say Spooner shot him in the chest.

Neither Spooner nor defense attorney Franklyn Gimbel has commented on the allegations. A message left for Gimbel wasn't immediately returned.

A jury found Zimmerman not guilty of second-degree murder in Martin's death. The case raised questions of whether the shooting was racially motivated. Zimmerman identifies himself as Hispanic and Martin was black.
