A man charged with first-degree murder in the Tuesday morning shooting of a 16-year-old girl told authorities he was looking for someone to rob before he fired into a car of teenagers.

Leland Lenaire Johnson Jr., 19, of Brandon, was ordered held without bail at his first court appearance Friday.

He was charged Thursday night in the slaying of Christina Marie Veltri, who was in a car with three friends about 12:40 a.m. Tuesday, planning a trip to Sarasota. They were parked outside Veltri's home in Brandon's Sterling Palms Court apartments.

Hillsborough sheriff's detectives said Johnson walked up to Veltri's car, asking to use a cell phone, but the occupants refused, angering him. As they prepared to drive away, Johnson fired a handgun six times into the car, deputies said.

Veltri died Tuesday afternoon at Brandon Regional Hospital. Two others in the car, Toni Marie Waltz, 18, and Leroy James Doane IV, 17, suffered minor injuries. They were treated at Tampa General Hospital and released. The car's fourth occupant, whose name was not released, was not injured.

Johnson told detectives he and a couple of friends had been hanging out in the parking lot, preparing to rob someone, sheriff's spokeswoman Debbie Carter said. His home address, an apartment at 1850 Providence Lakes Road, is about a half-mile from Veltri's home.

Deputies pulled Johnson over about 5:10 p.m. Tuesday near Clifford Sample Drive and Causeway Boulevard. They said he was driving a car similar to the description of the one used in the shooting. He was charged with driving without a valid license and carrying a concealed firearm, an automatic handgun.

However, it turned out that the car Johnson was driving when arrested was not the one used in Tuesday's shooting. That vehicle, a 1995 gold Nissan Maxima, belonged to an acquaintance of Johnson's and was discovered at Riverview High School, Carter said.

No one answered the door at the Veltri or Johnson apartments Friday afternoon. Johnson was being held without bail at Orient Road Jail.
