Police called to the scene of a west Salt Lake City domestic disturbance ended up in a prolonged SWAT standoff with a possibly armed man inside a home on Friday.

But after six hours of demands over a bullhorn to surrender, a video camera on a robot sent inside the residence on Sir Jeffrey Circle, near 600 North and Starcrest Drive (1900 West) couldn't locate the suspect. Just before noon, SWAT officers moved inside to conduct a more detailed search.

No trace of the 26-year-old suspect was found, and the case turned into a wider search for the 5-foot-11, 200-pound Pacific Islander, alleged to have assaulted his wife and her grandmother.

Salt Lake City police Detective Veronica Montoya said that a 911 call came in at 5:27 a.m. from the two women, who fled the residence after an argument with the suspect inside turned violent. The suspect reportedly has a past history of domestic violence.

The women told police the man may have a firearm. Officers cordoned off the street from 600 North to 700 North and called in SWAT.

Montoya said the man was not believed to have a working telephone, so SWAT negotiators had attempted, without success, to talk him out using the bullhorn.

There was no response from inside, so police waited for a judge to approve a search warrant. About 11:15 a.m., a robot was deployed inside the house.

"Nothing," Montoya said. "The robot didn't find a thing."
