CHARLESTON, W.Va. -- Police are "exploring the possibility" that Charles Eugene March, who allegedly killed his co-worker two years ago, could be connected to other disappearances or unsolved homicides.
Meanwhile, police are investigating after someone broke into his alleged victim's house sometime this week.
March, 60, is accused of strangling Sheila "Kathy" Goble, 62, on April 24, 2010. The two worked together for more than 10 years at Kelley's Mens Shop on the West Side.
Police said March's son called authorities on April 25 -- one day after the two-year anniversary of Goble's disappearance -- after finding what appeared to be human remains in a shallow grave at his father's home.
On Wednesday, the state medical examiner's office confirmed that the remains found in March's yard were Goble's, and that she was strangled.
During questioning, March told Kanawha County sheriff's deputies he dismembered Goble's body and buried it behind his trailer the next day, according to a criminal complaint in Kanawha County Magistrate Court.
Kanawha County Prosecuting Attorney Mark Plants said investigators are "exploring the possibility" March could be connected to similar crimes.
"He is innocent until proven guilty. However, generally when a criminal defendant commits this type of crime, it's rarely the first time," Plants said. "These types of crimes are done -- if they have gotten away with it -- over and over again."
Plants said he would not confirm any open investigation into similar crimes, just that police are researching.
Kanawha County Sheriff's Lt. Sean Crosier said he's not aware of any missing person cases or unsolved homicides with connections to March.
"I don't believe [detectives] have reason to say he had done anything else," Crosier said. "I will say, with something he's alleged to have done at his age, it's not totally out of the realm for that to be his only time."
March's co-workers called him friendly and soft-spoken, and have said he showed no signs of guilt during the two years police searched for Goble. He told no one of the alleged crime, police said.
Hillcrest Drive break-in
Also, police are searching for people who entered Goble's vacant house on Hillcrest Drive earlier this week, said Charleston Police Sgt. Bobby Eggleton.
Eggleton said Charleston officers answered the call, but Kanawha County Sheriff's Detective B.K. Carper is investigating.
Crosier said he does not believe the break-in, which happened Monday or Tuesday, is connected to the homicide investigation.
Goble's sons maintained the house, said family friend Billy Herrald. He did not know if any items were stolen from the house.
"They [her sons] haven't really sorted through the inventory yet," Herrald said.
The break-in is another blow to an already grieving family, he said.
