ZEPHYRHILLS, Fla. (AP) — Police in a town near Tampa say a missing former writer for the 1980s cartoon series "Thundercats" was killed. Authorities have charged charged the victim's roommate, 45-year-old James W. Davis, with murder, MyFoxTampaBay.com reported. 

Investigators say they have forensic and video evidence linking Davis to the crime and say that "drugs and monetary renumerations" were involved in the crime.

Stephen Perry's van was found abandoned at a Tampa hotel May 16, with a severed body part nearby. The Zephyrhills mayor has said it was an arm, but police declined to provide details — including whether Perry's body has been found or why they declared him a homicide victim Thursday.

Perry's home was found ransacked and two roommates were also missing. They have since been arrested on unrelated charges but called "persons of interest."

Perry's wrote for numerous comics and scripted the "Silverhawks" cartoon. But friends say he never made much money. He was recently broke and had trouble finding health care for his potentially fatal bladder cancer.
