Garrido had just handed them the marijuana when the Pattersons and at least one of the other men pointed their guns at him, according to an arrest affidavit. Garrido then took out his gun and fired at them. They shot back and Garrido was killed.

Detectives believe Dajuan then walked up to Garrido’s car and shot Ceballos, who was sitting in the front passenger seat. She also died from her injuries.

The brothers were arrested Wednesday at an apartment in Biscayne Park, not far from where the fatal shooting occurred. They were arrested on two counts of second-degree murder with a deadly weapon.

Dajuan Patterson was booked into the Juvenile Assessment Center. Demetrise Patterson is being held without bond at the Turner Guilford Knight Correctional Center.
