A man suspected of holding a woman hostage in a Caesars Palace hotel room was wanted in Colorado, according to court records.

An arrest report released Wednesday said Matthew Mannix, 35, was holding his girlfriend hostage in room 2128 for nearly five hours, threatening to cut her tongue out and open fire on authorities.

Mannix appeared briefly in court Wednesday afternoon, when Justice of the Peace Rebecca Saxe ordered him held on a $750,000 bail. The judge said she was concerned that Mannix, who is from Colorado, would not appear for future court dates due to a fugitive warrant out of Colorado, active protective orders against him, and the violent nature of Tuesday’s alleged kidnapping.

Hotel security received multiple noise complaints just after 9 a.m. Tuesday, but when they knocked on the door, Mannix warned, “if you don’t leave it will end badly,” according to the arrest report from the Metropolitan Police Department.

The woman inside yelled to police “he has a knife,” but Mannix claimed he had a “magazine full of rounds,” police wrote in the report.

Detectives found the knife but no other weapons in the hotel room.

Mannix is accused of breaking the windows in his room and throwing large furniture down 21 floors to the pool below. The woman later told police she feared he was going to throw her out the window.

“The damage was some of the most severe property damage that I have seen in my 18 years as a detective,” an officer wrote in the report.

Police said they suspected he was smoking a meth pipe in the room, and he and his girlfriend were suspected of being impaired when they spoke to officers.

“Mannix was so high that he was paranoid and had a schizophrenic episode where he was yelling out random comments and numbers and saying that he would pay for everything because he has a lot of money,” police wrote in the report.

In court on Wednesday afternoon, prosecutors said Mannix was convicted of kidnapping in 2022, and had a property damage conviction from 2012. He also has four active protection orders against him.

Court records show Mannix was booked on charges of kidnapping, coercion with force or threat of force with a deadly weapon, destroying more than $5,000 in property, resisting a public officer with a deadly weapon that is not a firearm, disregarding safety of people or property and being a fugitive in another state.

He is being held without bail in the Clark County Detention Center.
