DAYTONA BEACH, Fla. -- One young boy was killed and an infant girl injured in a shooting early Thursday morning in Daytona Beach.

• 2 young children shot in Daytona Beach
• Young boy died at hospital, girl has wrist injury
• Suspect thought to be boyfriend of kids' mom

The shooting victims are a 10-year-old boy and a 5-month-old girl. The boy died at a hospital.

Daytona Beach Police investigators think both children were shot with a rifle.

The shooting happened on the 100 block of Center Street just before 6 a.m.

Police say the suspect, Terrence H. Young, fled the scene but was taken into custody a short time later.

A family member of the children thinks he was the mother's boyfriend.

“I told her to get that guy out of the house, (but) she wouldn’t listen," said Antonio Harrison, who identified himself as a great uncle of the children. "He said he’s from Miami; he would do what he wanted to do. ... It takes an evil person to kill some kids."

The infant was shot in the wrist and was transported to Arnold Palmer Hospital for Children in Orlando. Her condition has not been released.

Police say Young had several outstanding warrants in Volusia and Miami-Dade counties for stalking and fleeing and eluding. 

The motive behind the shooting is still being investigated.
