DULUTH -- Duluth police believe they know who stole Donald Singer's Porsche, but they're not saying he's responsible for the 57-year-old's murder.
Arrest warrants were issued Wednesday for 52-year-old Robert Craig Sandman. He has been charged with stealing the 1988 Porsche 944 noticed missing after Singer's daughter discovered his body inside his Montheath Pass garage.
Sandman has not been charged with murder, but authorities are actively searching for him and the vehicle bearing Georgia tag ADK6725.
"The investigation is ongoing, additional charges and/or additional suspects may be pending," Duluth Police Capt. M.A. Hunter said in a news release.
Gwinnett County Detention Center records showed Sandman, believed to be a Calhoun resident at the time of his arrest, was released from jail in February after serving about 10 months on theft by taking and aggravated stalking charges.
Court records showed that last March a woman living on Montheath Pass -- the same street as Singer -- filed for a permanent restraining order against Sandman. On March 14, that protective order was granted.
Singer was found Thursday afternoon, wrapped in blankets in his home's garage. Responding officers noted a strong smell of bleach and a broken window pane on the home's back door. The specific cause of death has not been released.
Anyone who comes into contact with Sandman, who also has a previous address in Cedar Rapids, Iowa, or the missing Porsche is asked to contact Duluth Police Det. Jimmy Purvis at 770-476-4151.
