Police fear that the child is also responsible for a fourth recent murder

Rapper Tramone Mitchell, 22, was shot in the face last weekend

A 15-year-old boy has been charged with shooting three people dead as they sat in their cars in a string of attacks in Birmingham, Alabama.

The unnamed child was arrested and charged with the deaths this week. Two of the victims were killed together in late October, the third on Saturday evening.

Kenneth Davidson, 34, and Shundria Peoples, 26, were found dead in their Ford Taurus in the early hours of October 23. They had been shot multiple times.

On November 14 Tramone Mitchell, 22, was shot in the face after being lured to what he thought was a drugs deal, AL.com reported.

No details of the suspect have been released other than his age and that he is black. A spokesman for the Birmingham Police Department said the boy has 'distinguished himself as a killer'.

Detectives suspect he could be behind a fourth killing, but have yet to elaborate.

Davidson, 34, and People, 26, were discovered in their car by officers after a police monitoring system picked up gunshots in a Birmingham suburb.

Mitchell, a rapper also known as Lil' Mone, was killed around 6:30pm on Saturday. He was shot in the shoulder and the face. His passenger was hit in the groin, but survived.

Second: Mitchell was shot dead near this intersection, not far from the site of the first killing, on November 14

The unnamed victim said that he and Mitchell had driven in their 2006 green BMW to an apartment complex just a few blocks from the first killing, thinking they were there to sell marijuana.

When the boy and another man arrived, the survivor said they opened fire then fled.

It is not clear what the boy has been charged with, as juvenile proceedings are kept secret.
