Police: 7-year-old boy killed in drive-by shooting while visiting family; no arrests made

Police say a 7-year-old boy was killed in a drive-by shooting Sunday while visiting family in southwest Miami-Dade for the holidays.

According to The Miami Herald ( ) Miami-Dade Police officer Juan Perez said the shooting, in Richmond Heights, about 24 miles southwest of Miami, involved a high-powered rifle.

Perez said no one was arrested, but one man was put in handcuffs "for his own safety" so he would calm down.

Police were searching for a Dodge Ram believed to be involved.

Miami-Dade Commissioner Dennis Moss said, "It's our worst nightmare realized."

Sunday evening, police had taped off much of the area as they continued to investigate.
