MINNEAPOLIS (AP) -- Investigators are looking into whether convicted murderer Donald Blom was involved in several other slayings in Minnesota, according to a broadcast report Monday.
WCCO-TV reported that Blom has told investigators he was at the crime scene of one slaying and might have been involved in another. Investigators began looking into other cases after Blom told a Bloomington police officer in a letter that he wanted to talk about other homicides.
However, when investigators visited Blom in Pennsylvania last summer -- while Blom was requesting a transfer to a prison closer to his family -- he rambled and made more demands, the station reported.
The cases being reviewed include the strangulation of Wilma Johnson, whose body was found near the St. Paul Cathedral in 1983, and the death of college student Holly Spangler, whose body was found in 1993 in a Bloomington park.
Blom told investigators he was at the scene of the Johnson slaying, though he denied killing her. He also said he might have killed a man near a bridge in St. Paul, though a body has never been discovered. Blom was initially a suspect in the Spangler slaying.

"We feel pretty strongly Donald Blom has been involved in a number of (killings)," said Dennis Fier, an investigator with the Minnesota Bureau of Criminal Apprehension who is looking into the cases.
Blom is serving a life sentence in a Pennsylvania prison for killing 19-year-old Katie Poirier, who was working at a Moose Lake convenience store when she disappeared in 1999. Blom was convicted of strangling her and burning her body on his nearby vacation property.
