SALT LAKE CITY – Another man is being held in custody as a possible witness in the disappearance of 14-year-old Elizabeth Smart, the U.S. Marshal's Office has told Fox News.
Douglas Rex Young, 51, was picked up on Sunday at the state prison when he went to visit a buddy.
A federal warrant turned up in the computer when Young gave officials at the prison his ID to get in.
Authorities say Young worked with Richard Ricci as a handyman in the Federal Heights area. That is the neighborhood where the Smarts live, however it is unknown at this time whether or not Young also worked in the Smart home.
The U.S. Marshal's Office says they took Young into custody and shortly thereafter Salt Lake City police and the FBI notified them they wanted to interview Young about the Smart case.
Police and the FBI were back Tuesday at Ricci's mobile home, taking bags of evidence they hope will lead to a break in the case.
Authorities carted off two bags after searching Ricci's home and shed for two hours. Investigators would not comment on what they took.
Ricci, 48, worked as a handyman for the Smart family a year ago. He is being held on an unrelated parole violation.
His father-in-law, Dave Morse Sr., said he used a key to open Ricci's trailer so authorities wouldn't have to break in.
"The police have definitely had a focus on Richard," Ed Smart, the missing girl's father, said Tuesday during the family's regular daily news briefing.
Detectives have said they have questions about Ricci's alibi June 5 — the day police say the girl was taken by gunpoint from her bedroom. Ricci has said he was home with his wife that night.
Ricci's wife, Angela, was not home during Tuesday's search. She was flying back to Salt Lake City after defending her husband in an interview Monday.
Through a statement released Friday by his lawyer, Ricci said he had nothing to do with the girl's disappearance. He said he has given 26 hours of police interviews, taken polygraph tests, given a blood sample, and surrendered the impounded 1990 Jeep Cherokee given him by Ed Smart as payment for work.
