, 31, turned himself in Monday for the murder of JaMarco Anthony
and shooting of his brother Jerrod Anthony
JaMarco was celebrating his 24th birthday on May 8
at an old VFW Hall in Alton when the party ended in gunfire.
According to the Alton Telegraph
, Mike has no criminal history and it's unclear why he may have shot the brothers. Alton police, meanwhile, say they're baffled that none of the 75-100 people at the party have voluntarily stepped forward to assist them in their investigation.
Mike is being held on a $1 million bond.
