Three Mount Vernon suspects face up to 25 years in prison if convicted of shooting a passerby during a late July gunbattle, the Westchester County district attorney's office said.

Prosecutors said 25-year-old Tyron McCallum, 24-year-old Kristopher Benjamin and 23-year-old Travis Clarke were "acting in concert" when one of them fired 10 shots at people in a car driving near the intersection of East Sidney and North Columbus avenues on July 25.

Instead of the intended victim, a 65-year-old woman who was a passenger in another car was shot. Police did not release details of the shooting at the time, and it's not clear how badly injured the victim was.

Police nabbed McCallum, Benjamin and Clarke in late September after a two-month investigation. On Thursday, prosecutors announced an indictment in which all three men were charged with second-degree attempted murder, first-degree assault and weapons possession, all felonies.

People in Mount Vernon "should not feel that the streets are a place of constant fear as their community is held hostage by handgun violence," District Attorney Janet DiFiore said in a statement.

McCallum and Clarke were jailed on $500,000 bail each, and Benjamin was sent to Westchester County Jail without the possibility of bail. They're scheduled for a court date on Oct. 23.

A message was left Thursday evening with Arnold Keith, a New York City-based lawyer who has represented McCallum in previous criminal cases. Court files additionally list Legal Aid as counsel for McCallum, and it's not clear whether Keith or Legal Aid is representing the Mount Vernon man in the attempted murder case.

A message was left Thursday evening with Paul Pickelle, a White Plains-based lawyer who represents Benjamin. Records show Clarke is represented by a court-appointed attorney, but the records do not include the attorney's name.

Thursday's announcement came less than two weeks after the shooting death of 34-year-old Harold Jackson on Sept. 30 after he was hit by several bullets outside the Ebony Gardens apartment complex on 151 S. Seventh Ave.

Police haven't made any arrests in that case and said they're continuing to investigate. Jackson's death was Mount Vernon's ninth deadly shooting of 2012.
