LONGMONT -- The Longmont man who killed three people Tuesday was arrested Sunday on suspicion of domestic violence against his ex-girlfriend, who was one of his victims in the early morning murder-suicide.

Daniel Sanchez, 31, was arrested on suspicion of false imprisonment, second-degree kidnapping, harassment and domestic violence after he threatened and attacked his ex-girlfriend on Saturday after learning she was seeing someone else, according to a Longmont police arrest report.

The woman, 25-year-old Beatriz Cintora-Silva, was among those Sanchez killed Tuesday. Sanchez also shot and killed his ex-girlfriend's sister, Maria Cintora-Silva, 22, as well as her husband, Max Aguirre Ojeda, 32, at the couple's home at 11464

Hot Spring.

Sanchez was released from the Boulder County Jail on bond just hours before the shooting, according to records.

According to a Longmont police arrest report, Sanchez met Beatriz Cintora-Silva near Longmont's Best Buy parking lot on Saturday to discuss repaying a $1,000 loan she gave him to fix his truck.

Sanchez drove that truck -- a white Dodge Ram with Texas license plates -- to the modular home where he shot three people and then himself around 4 a.m. Tuesday.

On Saturday, Sanchez reportedly became angry with Beatriz Cintora-Silva when she received a text message from her new boyfriend, according to the Longmont police report. Cintora-Silva told police that Sanchez drove her to a "dirt farm road" near what she thought was the Walmart Supercenter, 2285 Ken Pratt Blvd., and slammed her against the dashboard when she tried to leave. Eventually, Sanchez dropped her back at the Best Buy parking lot, according to the report.

Cintora-Silva told police that Sanchez had been verbally and physically abusive during their four-year relationship.

"He has threatened to hurt her if she ever contacted police or told anyone about him being abusive," according to Sanchez's arrest report.

"Beatriz stated she has lived in fear and could not get away from Daniel during their relationship."

The report also mentions an incident on Thanksgiving in which Sanchez, who was drunk, got angry with Cintora-Silva for going to the basement to nap. According to the report, he pulled her out of bed, threw her against the wall and threw food at her, telling her to leave, according to the report.

Sanchez's home at 174 Mount Massive Way, in northeast Longmont, was wrapped in police tape on Tuesday, and a patrol car watched over the scene.

Boulder County property records show that Christopher White owns the home. He declined to speak with a reporter Tuesday afternoon. Neighbors said that White rents rooms to two other men,

including Sanchez, who lived in the basement.

Neighbor David Pierce, who lives across the street from 174 Mount Massive Way, woke up at 6 a.m. and saw yellow crime scene tape around the home. Patrol cars remained at the scene in the morning and early afternoon. At about 1:30 p.m. officers searched the home and took out several bags of items.

The two-story, cream-colored home with red trim and a brick faade, sits on a quiet street in northeast Longmont. Neighbors said the community is close.

Pierce said he interacted with Sanchez a few times.

"He seemed like a nice guy to me. He seemed pretty mellow," he said.

Donna Gissel, who also lives across the street from 174 Mount Massive Way, said that Sanchez moved into the home about 11/2 years ago. She called Sanchez a "wonderful guy" who was "really, really nice."

"I've never seen a bad side of him. Never seen him angry. He was a happy guy, fun to be around," she said.

Gissel said that Cintora-Silva moved into the home about six months ago. The couple enjoyed cooking and baking, she said, and invited neighbors over for dinner.

"As a couple, they seemed really happy," she said. "They seemed like they were in love a lot."

Gissel said Sanchez shared with her that the couple had broken up around Thanksgiving, and Beatriz Cintora-Silva moved out of the home and was staying with her sister and brother-in-law.

"It's breaking my heart," she said, tearing up. "I can't believe

he took it that hard. (Cintora-Silva) didn't deserve it. He didn't seem like that type of person."

Gissel said she did not know of abuse in the relationship. She said she witnessed one tense moment between the couple once while watching a Broncos game at their home. She said the incident made her uncomfortable enough to leave.

"You never imagine something like this happening in your neighborhood," she said.
