Man in Aryan Brotherhood is accused in crime spree

An Aryan Brotherhood gang member faces a slew of charges related to the back-to-back shootings Saturday of a mail carrier in the Spring Branch area and a man at a nearby Costco gas station.

Police say Matthew Williams shot the mail carrier around 2 p.m. and drove to the gas station, where he allegedly attempted to shoot another man less than five minutes later.

Then, he sped out of the parking lot in a black Honda Fit — which he is accused of stealing the day before from an ex-girlfriend — collided into a vehicle and sped off without stopping, charging documents show.

Williams, who is a documented member of the white supremacy prison gang, is being held without bail after his arrest on Monday, according to court records.

The crime spree began on Friday, when Williams’ ex-girlfriend called police to her home in Katy. She said Williams took the keys to her car and home, and had a handgun. At one point, he was outside of her house, yelling for her and claiming he would “kill her if he knows the police are coming.” He said “the only way he’s leaving the house is if there is a shootout,” she told authorities.

When deputies arrived, the ex-girlfriend said that they should forget about what she initially reported.

Williams resurfaced at 2 p.m. on Saturday, when he allegedly shot a U.S. postal worker who was delivering mail on Cedardale Drive. Witnesses reported hearing as many as four gunshots, and officers on the scene said the carrier had bullet wounds to the back and stomach, the documents

show.

The postal carrier, identified as 30-year-old Adrian Jackson, was taken to an area hospital in an unknown condition. He later told police that the gunman, a white man with facial tattoos, was driving a black hatchback

Just 1.5 miles away after 2:02 p.m., at the Costco gas station on 1150 Bunker Hill, a driver pointed a gun out of the window of his black vehicle and shot a Costco employee walking toward him, authorities said. The employee only suffered a scratch on his face, authorities

said. The gunman tried shooting the man again, but he fled after his gun misfired or jammed, authorities said.

The elderly employee, who police say is black, told a gas station attendant that a white man with face tattoos aimed at him from inside his car.

Parking lot surveillance video showed the incident, as well as the gunman’s attempt to flee . The driver, who police later identified as Williams, rearended a woman’s car as she tried to exit the parking lot, according to court records. The woman took a photo of the vehicle – a black Honda Fit – which police tracked to Williams’

ex-girlfriend.

High on drugs, he drove to his brother’s house and confessed to shooting the mail carrier, the brother told police.

Williams was arrested Monday on five felony charges – felon in possession of a weapon, theft of a motor vehicle, aggravated assault with a deadly weapon, violating a protective order set forth by the ex-girlfriend and aggravated assault against a public servant.

The 24-year-old, of Katy, also faces a misdemeanor charge that accuses him of failing to stop and give information after the wreck at the Costco parking lot.

Spokespeople with the

Houston Police Department declined to comment beyond a news release issued Thursday. The U.S. Postal Inspection Service, the Bureau of Alcohol Tobacco and Firearms and the city police department participated in the investigation.

It’s unclear whether the shootings are believed to be race-related. The mail carrier’s race is unknown.

At the time of the shooting, Williams was out on bond on a terroristic threat charge related to his ex-girlfriend. He has prior felony convictions for criminal mischief, cocaine possession and evading arrest.
