Police say they’re uncertain why a man with a misdemeanour on his record and no warrant for his arrest erupted in a spate of violence after a routine traffic stop in West Texas, killing seven, including a man outside his parents’ home and a teenager shot as she left a car dealership with her family.

Authorities said Seth Aaron Ator, 36, also injured 22 people Saturday afternoon before officers killed him outside a busy movie theatre in Odessa.

Online court records show Ator was arrested in 2001 for a misdemeanour offence that would not have prevented him from legally purchasing firearms in Texas, although authorities have not said where Ator got the “AR-style” weapon he used.

Authorities said those killed were between ages15 and 57, but did not immediately provide a list of names. But family and employers said the dead include:

  • Edwin Peregrino, 25, who ran out of his parents’ home to check out the commotion.
  • Mary Granados, 29, a mail carrier slain in her U.S. Postal Service truck.
  • Leilah Hernandez, a 15-year-old high school student, who was walking out of an auto dealership.

Hundreds of people gathered at a local university in the Permian Basin region known for its oil industry Sunday evening for a prayer vigil, to console each other and grieve the loss of life.

“We’re out here in the middle of nowhere,” Midland Mayor Jerry Morales told the crowd. “All we’ve talked about is oil forever. And then this happens.”

Odessa police Chief Michael Gerke said there were still no answers pointing to a motive for the attacks, which began when Texas state troopers tried pulling over a gold car on Interstate 20 for failing to signal a left turn.

Before the vehicle came to a stop, the driver “pointed a rifle toward the rear window of his car and fired several shots” toward the patrol car stopping him, according to Katherine Cesinger, spokesperson for the Texas Department of Public Safety. The gunshots struck a trooper, Cesinger said, after which the gunman fled and continued shooting. He fired at random as he drove in the area of Odessa and Midland, two cities more than 480 kilometres west of Dallas.

Police used a marked SUV to ram the mail truck outside the Cinergy Movie Theater in Odessa, disabling the vehicle. The gunman then fired at police, wounding two officers before he was killed.

“Local law enforcement and state troopers pursued him and stopped him from possibly going into a crowded movie theatre and having another event of mass violence,” FBI special agent Christopher Combs said.

An already violent month in Texas

Police said Ator’s arrest in 2001 was in the county where Waco is located, hundreds of kilometres east of Odessa. Online court records show he was charged then with misdemeanour criminal trespass and evading arrest. He entered guilty pleas in a deferred prosecution agreement where the charge was waived after he served 24 months of probation, according to records.

The shooting ended an already violent month in Texas, where on Aug. 3, a gunman in the border city of El Paso killed 22 people at a Walmart. Sitting beside authorities in Odessa, Abbott ticked off a list of mass shootings that have now killed nearly 70 since 2016 in his state alone.

“I have been to too many of these events,” Abbott said. “Too many Texans are in mourning. Too many Texans have lost their lives. The status quo in Texas is unacceptable, and action is needed.”

But Abbott, a Republican, remains noncommittal about imposing any new gun laws in Texas at a time when Democrats and gun-control groups are demanding restrictions. Even as Abbott spoke, a number of looser gun laws that he signed this year took effect on the first day of September, including one that would arm more teachers in Texas schools.

‘What’s the world coming to?’

Saturday’s shooting brings the number of mass killings in the U.S. this year to 25, matching the number in all of 2018, according to The AP/USATODAY/Northeastern University mass murder database. The number of people killed this year has already reached 142, surpassing the 140 killed last year. The database tracks homicides where four or more people are killed, not including the offender.

Daniel Munoz, 28, of Odessa was headed to a bar to meet a friend when he noticed the driver of an approaching car was holding what appeared to be a rifle.

“This is my street instincts: When a car is approaching you and you see a gun of any type, just get down,” said Munoz, who moved from San Diego about a year ago to work in oil country. “Luckily I got down…. Sure enough, I hear the shots go off. He let off at least three shots on me.”

He said he was treated at a hospital and is physically OK, though bewildered by the experience.

“I’m just trying to turn the corner and I got shot — I’m getting shot at? What’s the world coming to? For real?”
