Two suspects have been arrested in connection with the killing a 12-year-old boy who was traveling in an SUV in Wilmington late last year, police announced Friday.

The two Wilmington residents, identified as 21-year-old Damian Ulysses Martinez, and 19-year-old Gabriel Martinez, were arrested on Tuesday, the Los Angeles Police Department stated in a news release.

Both men were booked on suspicion of murder in the shooting death of Alexander Alvarado, the LAPD stated.

The shooting occurred on Dec. 6, 2021, as Alvarado was traveling with his family in the front passenger seat of a black Dodge Durango in the area of Denni Street and Blinn Avenue.

Gunmen opened fire on the SUV, striking Alvarado, the driver, and a 9-year-old girl who was on a nearby playground at Wilmington Park Elementary School, police said.

Alvarado later died from his injuries.

The driver of the SUV, identified as Alvarado’s 25-year-old stepmother, was shot in the stomach but survived.

Investigators said the 9-year-old girl was hit in the back by a stray bullet and also survived.

Alvarado’s 10-year-old brother was in the SUV at the time of the shooting but was not struck.

“This was a brazen assault in the middle of the day that, whether it was targeted in a pre-emptive manner or a premeditated manner or spontaneous, I just know that the amount of violence was just … It just boggles your mind when you think about an afternoon outside of a school,” LAPD Chief Michel Moore said following the incident.
