Tom Sizemore called into questioning regarding missing girlfriend

Actor Tom Sizemore's girlfriend, Megan Lacy Wren, has been missing for over a month now.

The LAPD confirms to KTLA on Thursday (May 12) that detectives have spoken with the "Natural Born Killers" star and "Celebrity Rehab" alum regarding the 25-year olds mysterious disappearance.

Law enforcement reps would not comment on whether Sizemore is considered a suspect or not, but his rep tells Radaronline that he was completely uninvolved with the case.

"This young lady is a heroin addict unfortunately," his manager explains. "Tom's been helping her out. He's been letting her sleep it off. He helps buy her food and gives her a little money. He sent her to rehab three times but she quits after two days."

This case only adds to the laundry list of substance abuse and domestic violence arrests that have been attached to the 49-year old's name over the years.

In 2003, he was convicted of assaulting then-girlfriend Heidi Fleiss.

Wren is an aspiring actress who was last seen on March 31 around Vermont Avenue and Wilshire Boulevard in Los Angeles. Anyone with information is encouraged to contact the LAPD or Crimestoppers.
