Erin Cash, the man accused of shooting his girlfriend's two brothers and an innocent bystander on Sunday, was taken into custody by U.S. Marshalls in Port St. Lucie on Monday afternoon, according to the arrest report.

On Sunday Cash, 23, got into a physical confrontation with his girlfriend in a car while their 3-year-old son was in the backseat. The girlfriend told police Cash was threatening her and their son.

Cash then dropped his son off at his mother's, the boy's grandmother's home.

He then went on a shooting spree, shooting two of his girlfriend's brothers, according to police. He shot the first brother near Northwest 12th Avenue and Northwest 64th Street, and the second two blocks away on Northwest 10th Avenue, police said. Both were grazed, one in the neck and the other in the arm.
