ST. LOUIS (AP) – A St. Louis man is now facing a murder charge after allegedly shooting a friend in the forehead after the friend asked him to do so.

Twenty-one-year-old Kevin Beindorff was originally charged with assault and armed criminal action.

The assault charge was upgraded to second-degree murder after 18-year-old Matthew Pellegrini of Ballwin died Thursday.

Beindorff is jailed on $300,000 cash bond and does not yet have a listed attorney.

Authorities say the men were in a vehicle outside Beindorff’s home Tuesday night when Beindorff showed a revolver. That’s when Pellegrini asked Beindorff to shoot him. Beindorff allegedly raised the gun to the victim’s forehead and fired one shot, then drove him to a hospital, where Pellegrini died.
