LITTLE ROCK, Ark. (KTHV) -- The U.S. Marshals have confirmed that Gary Holmes has been arrested in the murder of three-year-old Acen King.

The U.S. Marshals assisted the Little Rock police in the case. Both law enforcement agencies worked with Holmes' family to convince him to surrender to police.

The 3-year-old's death is the second child fatally shot in a car within a month and the 40th homicide on the year for the city.

He was killed while riding in his grandmother's car. Neither the grandmother, Kim King-Macon nor Acen's one-year-old sibling were harmed in the shooting.

Court records state that Holmes will have a video arraignment on Friday.
