MOUNT VERNON, Wash. — The man accused of killing five people at Macy’s store in a Washington state shopping mall before leading authorities on a nearly 24-hour manhunt was charged Monday with five counts of first-degree murder.

Arcan Cetin, 20, made a brief appearance in Skagit County District Court and his bail was set at $2 million. Court documents released before the hearing said Cetin confessed to the slayings after his arrest, telling detectives who interviewed him that “he did bring the rifle into Macy’s and shot all 5 victims.”

Cetin was arrested Saturday, a day after the gunman opened fire in the department store’s cosmetics department Friday night, killing a man, a teenage girl and three women.

His stepfather said after Monday’s court appearance that Cetin had unspecified mental health problems.

“The only thing that we want to say at this time is that we both are totally devastated by what happened,” said David Marshall, who attended the hearing with Cetin’s mother.

Cetin’s lawyer, Keith Tyne, did not speak with reporters.

Cetin was described by one neighbor as so “creepy, rude and obnoxious” that she kept a Taser by her front door. He also had a string of run-ins with the law in recent years, including charges he assaulted his stepfather.

Cetin immigrated to the U.S. from Turkey and is a legal permanent resident, officials said. He is expected to make an initial court appearance Monday.

Authorities have not released information about a possible motive.

The Seattle Times reported that court records show Cetin faced three charges of assaulting his stepfather. The newspaper said Cetin also was arrested on drunken driving charges. It gave no details on when the arrests took place or how the cases may have been resolved.
