Andrew Lopez Confesses To Murder Of Zurana Horton In Brooklyn Shooting

An 18-year old male confessed to the gang related murder of a Brooklyn mother who tried to protect a group of school children from harm by shielding them.

The suspect, Andrew Lopez, was among three teens arrested on Tuesday for the shooting that took place last Friday outside a Brownsville school that claimed the life of 34-year old Zurana Horton.

Horton died instantly from a shot in the face and chest when she attempted to protect students from gunfire. Horton was the mother of 12 children.

Lopez was reportedly aiming for an 11-year old girl whom he was in a dispute with over a cell-phone.

The 11-year old girl survived an injury on her arm and graze wound on her face.

Lopez and his brother Kristian, who was also arrested, are believed to be members of a gang called 8 Block.

Police Commissioner Ray Kelly commented on Lopez in a briefing:

We're certainly pleased with the fact that the investigation has identified Mr. Lopez and he's made statements and apparently made a full confession.

Browsnville is among the most crime-ridden neighborhoods in the city. Since the shocking shooting, community members, including Rev. Al Sharpton who met with Horton's family, have called for an end to gun violence.
