Chandler police said Laiaddee, 33, was last seen on March 18. Detectives said Laiaddee's live-in boyfriend, Valentini, has been named a person of interest in her disappearance.

KPHO reports that after arresting Valentini on an outstanding traffic warrant May 28, police searched his apartment and found two debit cards, an American Express card and a health insurance card that belonged to Laiaddee, according to the documents.

The court documents say Valentini "did admit" to using one of the cards to pay his bills. The documents also show there were charges for an adult dating website on the card.

Police also found a handgun, rifle and dozens of rounds of ammunition in the apartment, according to the report. Valentini is prohibited by law from possessing guns due to a 2007 felony trespassing conviction.

Police said they discovered Valentini's real identity during the Scottsdale apartment search. Officers found an envelope containing documents addressed to Rick Valentini, including divorce records. There was also a Michigan driver's license under that name.

Laiaddee, 32, was reported missing once her estranged father spoke with Valentini - he was concerned about his daughter's whereabouts after not speaking to her for more than 10 weeks, say police. Detectives learned that Laiaddee was last seen by her boyfriend at her Chandler, Ariz. home located outside of Phoenix.

Valentini, 41, worked at Gold's Gym in north Scottsdale and had previously been fired for sexual harassment allegations, said AZ Central. According to the site, Valentini told police that he and Laiaddee broke up because she was moving to Denver for a new job.

He is currently being held without bond in a Maricopa County jail, said AZ Central on weapons, forgery, and credit card theft charges, according to AZ Central.

Laiaddee is still missing. She is described as 5-feet-4-inches tall, 130 pounds, and has dark brown hair and brown eyes and she is of Taiwanese descent.
