What we know:

According to Mesa Police, officers on Nov. 5 responded to a domestic violence call at a home near University Drive and Greenfield Road. Once at the scene, police found a woman with multiple injuries.

Mesa Police said the incident involved a fight between 33-year-old Thomas Zambrano and his 27-year-old girlfriend.

After the woman was taken to a hospital for an injury to her face, Zambrano barricaded himself inside a house on Caballero Street.

"Officers later observed the suspect holding what they believed to be a rifle. He was also making threats towards the officers," Mesa Police Det. John Dreyer said.

Police evacuated homes up and down the street. SWAT teams surrounded the house, and after deploying tear gas the first time, police said Zambrano fired multiple shots, one of which struck a nearby home.

"That homeowner did sustain minor injuries as a result of the glass from when that bullet went through the window," Detective Dreyer said.

Tactical teams used a robot, police dogs, and drones during the standoff. Over a loudspeaker, police offered to help Zambrano.

"I heard them say 'everything is OK, we still love you, everything is alright. Come out and talk to us,'" Robert Cruz said. Family members were also heard yelling for him to cooperate.

Zambrano eventually turned himself in, and he was transported to a hospital for tear gas exposure and injuries to his back. His dog was taken from the scene and given to family members.

Zambrano is accused of multiple charges, including aggravated assault and resisting arrest.

What we don't know:

The woman's current condition is unknown.

Police haven't released any details on what led up to the incident.

What they're saying:

Cruz, who lives in the area, said he had to evacuate his home with his children.

"There was a banging on my front door, so I opened it, and it was the police telling me, 'How many are in your house? We have to escort you out. There's a situation going on with one of your neighbors,'" Cruz said. "So we got dressed, grabbed our things, me and my kids we got in the car, they moved out of the way, so we were just able to get out of our driveway, and we're still here observing what's going on."
