Two men died and seven people were wounded Friday night in what police are calling an ambush-style shooting that occurred as the group filmed a music video in northern Harris County, Sheriff Ed Gonzalez said.

A group of teens and young men came under fire around 9:30 p.m. from unknown assailants who quickly fled the area, sheriff’s officials said. The shooting happened in the parking lot of an industrial warehouse bordering a residential neighborhood, about a quarter-mile east of Interstate 45 between West Little York and West Gulf Bank roads.

Here’s the scene where 9 people were shot — and two killed — last night just north of Houston. Police are no longer here, but there’s still quite a bit of blood, and bulletholes in a few cars/windows nearby. pic.twitter.com/XWgXkOvmjp — Robert Downen (@RobDownenChron) December 28, 2019

“All of a sudden, basically they were ambushed, we believe by individuals in cars and/or foot that fired shots into the parking lot area,” Gonzalez said in a media briefing.

Two men died at the sceene — Gonzalo Gonzalez, 20, and Jonathan Jimenez, 22 — and the wounded were transported to multiple hospitals in the area, sheriff’s officials said. Gonzalez described some of the injuries as “very serious,” with one victim in critical condition after he was shot in the head. No additional details on their health were released.

“We believe there could still be more (victims) that are injured that happened to leave the scene before we got here,” Gonzalez said.

The wounded victims were identified as Jordan Diaz, 17; Jorge Gonzalez, 19; Miguel Guajardo, 20; Moses Alvarez, 21; Miguel Martinez, 21; Fabian Garza, 22; and Abel Pesina, 23.

Sheriff’s officials did not have any suspect or vehicle descriptions to release in the hours after the shooting, and no updates were available as of Saturday evening. Investigators are working to determine a motive for the shooting.

“We don’t know if there was a beef going on or what exactly happened. That will be part of the investigation,” Gonzalez said.

The industrial warehouse is home to several small organizations, including a display graphics manufacturer, mortuary and storefront church. A cluster of trees and overgrown shrubs shields the area from residential houses.

Gonzalez said investigators were canvassing the area to identify any residents or businesses with surveillance cameras. No residents living near the industrial zone were injured.

Multiple efforts to reach family members of the victims were unsuccessful Saturday.

Hour after the shooting occurred, blood still stained the parking lot, and a pair of lights that were used for the video shoot were still standing. A bus shelter, nestled between the lot and the street that the assailants likely fired from, had four visible bullet holes. A nearby car was also struck.

The scene was otherwise quiet — save for an older group that arrived in the late-morning to pick up a vehicle and the leftover lights. Before departing, they each briefly stared over the bloody pavement, and some broke into tears.
