A 6-year-old boy was killed Wednesday night as horrified relatives watched the same driver hit him twice before driving off at a Miramar McDonald’s, police said.

D’Andre Binns was pronounced dead at Joe DiMaggio Children’s Hospital and Miramar police have been searching, so far in vain, for the killer who drove a white car, possibly a Dodge Charger with 22-inch rims.

“Why could someone so wicked hit a baby and run?” D’Andre’s grandmother, Shirley Adams, sobbed in an interview with Miami Herald news partner CBS4.

“He’s a nice little boy. He was a nice little boy,” she said. “He laughed with you, a very pleasant child.”

Police spokeswoman Tania Rues described the situation as “horrific.”

“We just need one phone call, one tip to catch the person who did this,” Rues said. “The car obviously has front-end damage, probably a shattered windshield. It should be easy to spot.”

D’Andre was hit by the white car about 8:30 p.m. as he crossed the 6200 block of Miramar Parkway in front of the McDonald’s where his family had just gotten food.

A relative, identified as either the boy’s uncle or father, was crossing the street with D’Andre’s cousin in his arms. He was probably unaware the boy was following him, Rues said.

That’s when the white car hit D’Andre, who smashed into the car’s windshield. The driver swerved multiple times and D’Andre fell off the car, Rues said. The car then ran over D’Andre, drove east on the parkway and then headed south on State Road 7/U.S. 441.

D’Andre and his mother were visiting from Wellington, the Palm Beach Post reported.

D’Andre’s mother, who was sitting in a parked car at the McDonald’s when he slipped away, saw her child killed.

“She is distraught,” Rues said.

Under a tree in front of the McDonald’s, the family set up a makeshift memorial of roses, a large teddy bear and a little stuffed doll of a smiling little boy.

A cousin, 17-year-old Racquel Leslie, said the doll was the family’s lasting memory of D’Andre.

“He’s a 6-six-year-old boy with great goals for his life,” she said. “He didn’t even get to make it through 2013. He was a great little boy with a big heart.”

Anyone with information should call Broward Crime Stoppers at 954-493-TIPS (8477).
