At least one person was killed and several others wounded in a shooting in Midland, Texas, on Friday morning, according to Mayor Lori Blong, who said there were 11 known victims. 

The suspect in the incident has died, the city said, but did not provide additional details.

Nine victims are being treated at Midland Memorial Hospital, with four still in surgery and five currently stable, the hospital told CBS affiliate KOSA.

“My heart breaks for the victims and their families,” Blong said. “We are praying for every person touched by today’s events and for the law enforcement officers who risked own safety to protect our community.”

Blong said she was not aware of any police officers being injured.

Midland Police Chief Greg Snow said in a social media post that officers heard gunfire coming from a building in the southwestern part of the city and they quickly secured the area.

A woman who was at the hospital where victims were taken told CBS News 24/7 she saw some casualties before being moved to a safe area as the hospital implemented a lockdown.

“My understanding is that the whereabouts of the shooter were not entirely known at the time. And we also wanted to stay out of the way of the essential hospital staff that needed to take care of patients,” the woman, who asked to only be identified as Jane, said.

The victims she saw appeared stable, she said.

The lockdown lasted for about an hour and a half, she said, adding there was “a sense of calm and professionalism” at the hospital.

Jane, who lives in the neighborhood of the hospital, said hearing about the active shooting made her feel scared and unsafe.

“It makes me really scared that there are people walking around with guns who are, you know, who can just kill you and kill anyone around you. And that makes me feel really unsafe and very scared,” she said.

Midland is in western Texas, about three hours south of Lubbock.

“Governor Greg Abbott and First Lady Cecilia Abbott are deeply saddened by the incident in Midland,” the governor’s press secretary, Andrew Mahaleris, said in a statement. “Our hearts are with the victims, their families, and the entire Midland community.”
