LONGMONT, Colo. (CBS4/AP) – Two men, a woman and a young adult female are dead from gunshot wounds in Longmont after what police are calling a triple murder-suicide.

The gunman has been identified as 31-year-old Daniel Sanchez. Police said he bonded out of the Boulder County Jail Monday around 10 p.m. after being charged with domestic violence against one of the victims in the shooting, his ex-girlfriend, 25-year-old Beatriz Cintora-Silva. He also shot her sister, 22-year-old Maria Cintora-Silva, and her husband, 32-year-old Max Aguirre Ojeda, before turning the gun on himself.

The shooting happened about 4 a.m. in the Longview Subdivision at 11464 Hot Springs, near Highway 119 and County Road 3 1/2. That’s in the eastern part of Longmont in Weld County, near Union Reservoir.

One of the women who was killed called 911 and told the dispatcher where she was, according to Weld County Sheriff’s spokesman Sgt. Tim Schwartz.

“Our dispatcher then heard the female party hollering ‘No, no, no’ … followed by gunfire,” Schwartz said. “A male caller then got on the phone and said he was going to kill himself. At that time the dispatcher then heard another gunshot.”

Soon after that the Weld County SWAT team entered the home and found the four bodies and found a handgun that Schwartz said had been fired multiple times.

Schwartz said his department is investigating whether there was a history of violence at the home and interviewing neighbors.

“He shot out the back door,” Weld County Sheriff John Cook said. “He shot that out then gained entry into the house.”

The bodies of Ojeda and his wife were found in one bedroom and Beatriz Cintora-Silva and Sanchez were found in another, Cook said.

Authorities found a .45-caliber Glock handgun near Sanchez’s body and 16 spent shell casings around the house, Cook said, adding that investigators were still examining the house and might find more.

Sanchez had been living in another house in the same neighborhood of tidy modular homes, winding walkways and parks. Investigators searching that home found the original box the handgun had been sold in, but they did not find a receipt, and it was unclear when he bought it, Cook said.

Cook said Sanchez had two magazines for the gun, and each held 13 rounds of ammunition.

Copter4 video after daybreak on Tuesday showed crime scene tape surrounding the house and its front yard. Christmas lights adorning the home were still illuminated, and there was a wreath hanging on the front of the home.

Eddy Silva says she is the aunt of Maria Cintora-Silva and Beatriz Cintnora-Silva.

“They just moved from a different country and for this to happen is just horrible,” she said.

The Weld County Sheriff’s Office said Beatriz Cintnora-Silva had recently broken up with Sanchez and moved into the home of her sister and her husband. On Sunday Sanchez was arrested and charged with domestic violence after hitting Beatriz Cintnora-Silva. According to deputies, Beatriz Cintnora-Silva was told not to return to the residence she shared with Sanchez and she turned down protection.

“Boulder County did their job. They notified her when he was released,” Schwartz said.

Schwartz said he hasn’t talked to the dispatcher who took the call, but he did say she and the officers who were first on the scene are most likely taking the situation hard.

“I would imagine she’s pretty shaken up,” Schwartz said.

Investigators believe jealousy was the motive for the shootings .

As investigators searched the home, a woman slipped under the crime tape and ran toward the house. The unidentified woman was restrained by police, fell to the ground on her knees and began crying before being led away.

A pickup truck with Texas license plates, meanwhile, sat idling in the driveway while police waited for permission to enter the vehicle. A neighbor said it had been running since morning.

Several neighbors described what happened around 4 a.m. Tuesday.

Joyce Vibbert said she heard three gunshots and a woman’s voice.

“It was just screaming. I couldn’t hear what she was saying. It was just screaming,” she said.

Vibbert said she couldn’t see what was happening from her bedroom window.

Kathy Tubb said she heard the shots at about the same time and had no idea what was happening.

She said when her husband went outside to warm up the car to go to work, she saw a policeman wearing a helmet and armed with a rifle standing in the street. Tubb said her husband was worried there might be a gunman still on the loose and feared for his life.

Desirae Swazoe said she awoke shortly after 4 a.m. and heard repeated shouting, “Weld County Sheriff’s Department! Open the back door! Do it now!”
