The boyfriend of a Florida police cadet who has been missing for over a year has been arrested. 

David Perry, allegedly the last person to see Kelly Rothwell, 35, before she was reported missing, has been arrested on grand larceny charges in Steuben County, New York, reports. 

Perry is accused of stealing in excess of $300,000 from New York State retirement disability fund over the past seven years. 

He is being held on $100,000 bond, reports. 

Monday marked one year since Rothwell disappeared from her Gulf front condo in Florida. Pinellas County Sheriff Bob Gualtieri called a news conference to recap the details in the cold case. 

He announced that Rothwell's family is offering a $25,000 reward and his office is offering another $25,000. 

The last day Rothwell was seen she told her friend that she was going to break up with her live-in boyfriend, Perry, a former New York state prison guard. 

Rothwell said she received a text message from Rothwell at about 6:30 the evening of March 12, 2011, but from the language and the way the text was written, she doesn't believe it came from her friend. 

Rothwell also failed to show up for a meeting to pick up the keys to her new apartment that day. 

Authorities searched the condo Rothwell and Perry shared and found a pristine, sterile environment free of evidence, a scene Gualiteri said was "almost too clean." 

A downstairs neighbor said he heard banging and vacuuming that night as well. 

Perry has been named a suspect in the case and authorities say he has not cooperated with the investigation. 

Rothwell was enrolled in a police academy and volunteering with a Florida domestic violence organization at the time of her disappearance, detectives found her notes in a trash bin. 

"That's contrary to everything we know about Kelly and contrary to common sense," Gualtieri said.

In October 2011, Perry was arraigned in New York State on unrelated insurance fraud and grand larceny charges in Elmira, N.Y. Police did not expect Perry to discuss Rothwell during the fraud and larceny trial.
