Georgia deputies arrested a man they say stalked his ex-girlfriend and tried to kill her and the couple’s infant on two occasions this week.

Marcus Issaih Calhoun, 25, was taken into custody Thursday on several felonies, including battery, aggravated stalking, robbery by sudden snatching, possession of a firearm during the commission of a felony and two counts of aggravated assault.

The Henry County Sheriff’s Office announced the arrest in a news release late Thursday. The Muscogee County Sheriff’s Office worked with Henry County deputies to track down Calhoun in Columbus after he got on a Greyhound bus headed to Alabama. Agency officials said he was trying to escape arrest.

Investigators said they found a gun in Calhoun’s possession on the bus.

According to authorities, Calhoun violated a temporary protective order when he showed up at his ex-lover’s McDonough home Tuesday and attacked her. Calhoun fled the home before officers arrived, but investigators obtained warrants for his arrest.

On Wednesday, authorities said he approached the victim while she was at Avalon Park with her child. Deputies said he fired several shots at a vehicle the woman and baby were in as she drove away from the McDonough park.

Calhoun is in custody at the Henry County Jail, according to the statement.
