The man who drove a vehicle into a group of people near a migrant shelter in Brownsville, Texas, on Sunday, killing eight and injuring 10 more, has been charged with eight counts of manslaughter, Brownsville Police chief Felix Sauceda said Monday.

The driver was identified as George Alvarez, a 34-year-old with an extensive rap sheet, including prior charges of assault and driving while intoxicated, according to police. The vehicle he was driving ran a red light, lost control, flipped on its side and hit a total of 18 people, the chief said. Alvarez then tried to flee the scene before he was detained by bystanders, police said.

He was charged on the manslaughter counts as well as 10 counts of aggravated assault with a deadly weapon, and his bond was set at $3.6 million, the chief said. Police said they are still investigating the cause of the crash.

Several immigrants were among those killed when the Land Rover hit the group waiting at a bus stop across the street from the Bishop Enrique San Pedro Ozanam Center, a non-profit homeless shelter helping to house migrants in the border town, authorities say.

Surveillance video of the incident shows the vehicle driving at a high rate of speed and hitting a curb about 30 feet from where the migrants were sitting before the driver appears to lose control, according to Victor Maldonado, the director of the Ozanam Center in Brownsville.

There were about 20 to 25 migrants sitting on the curb at around 8:30 a.m. when police reported receiving reports of the crash, according to the shelter’s director. The migrants were from Venezuela and had arrived at the shelter just days ago, Maldonado said.

“The staff and residents of the Ozanam Center are devastated by Sunday’s tragic event,” Maldonado said in a statement. “The individuals injured and killed are asylum-seekers. They came seeking refuge. They were staying at our shelter because they arrived in this country with very little.”

The driver received medical care and was arrested on suspicion of reckless driving, Brownsville Police spokesman Martin Sandoval said. Seven victims are still in the hospital and three have been released, Sandoval told CNN Monday.

The fatal crash comes as border towns like Brownsville are bracing for a migrant surge when the public health emergency measure known as Title 42 lapses on Thursday. US Customs and Border Protection officials already have seen an uptick in migrants at the border with Mexico in anticipation of the expiration of Title 42.

CNN interviewed migrants staying at the Ozanam Center in December. At the time, the center’s director said migrants from all over the world were starting to stay at his shelter and he was seeing an uptick in stays.

Located on the southern tip of Texas, Brownsville’s population is nearly 95% Hispanic or Latino, according to the 2022 census.

The city recently declared a state of emergency after receiving an influx of thousands of migrants, many from Venezuela, in the past several weeks, CNN previously reported.

Video shows bystanders detained driver

A law enforcement officer investigates a damaged vehicle after it ran into pedestrians near Ozanam Center, a shelter for migrants and homeless, in Brownsville, Texas, on May 7.

After the crash, witnesses at the scene detained the driver until officers arrived, police said. Exclusive video obtained by CNN shows a group of people trying to restrain the man after the crash.

Cesar Romero, 34, is a Venezuelan national who said he witnessed the crash and saw his friends run over by the vehicle.

“Some of the men killed had just arrived the night before,” he said while tears rolled down his face.

Romero said after the crash, the driver exited his vehicle and appeared to be impaired. He said the driver tried to run away and yelled obscenities, but witnesses stopped him.

Sandoval told CNN that investigators were made aware of the video Monday morning.

“The video is part of a separate incident investigation but related to the accident,” Sandoval said. “We are looking at what the DA can formulate from the video to see if they have enough to potentially face charges.”

“We are looking at it three different ways,” Sandoval said. “One, to see if he was intoxicated. We took a blood sample, and we have to turn
