San Francisco prospect Angel Villalona is the main suspect in the killing of a 25-year-old man.

The Dominican prospect turned himself in 12 hours after the man was shot at a bar in the southern coastal city of La Romana, according to The Associated Press.

Villalona was signed by the Giants in 2006 and received a club-record $2.1 million signing bonus.
