MAZOMANIE (WKOW) -- The family of a man who had a form of autism, is accused of killing him and hiding his body.

In September, authorities learned Matthew Graville, 27, who had Aspberger's Syndrome, hadn't been seen by family members since June. On Monday, they found his body in rural Sauk County.

This spring, Graville moved into a Mazomanie home with his half brother Jeffery Vogelsberg, 27. Authorities say he wanted to be with someone he looked up to. In September, his step-grandfather alerted authorities, worried they hadn't heard from Graville in a while.

Dane County Sheriff Dave Mahoney says the office learned through interviews that Vogelsberg had mentally and physically tortured Graville for several months while they lived together. Officials believe that torture ended on July 1st, when Graville was killed. His body was found frozen and buried.

"Matthew lived a living hell," says an emotional Mahoney. "One in which he could only find peace in death."

The brothers were renting the home from Robert McCumber, 28. McCumber is in custody, for helping hide Graville's remains. He's the one who led authorities to the body, and told them he helped bury it.

Vogelsberg is also in custody, facing charges of first degree homicide and felony hiding a body.

Graville's step mother Laura Robar is also in custody. She's accused of conspiring to hide Graville's body, along with identity theft for taking money out of Graville's bank account and using his food stamps after he died.
Emily Schmit went to high school in Mount Horeb with Graville. She says he was a bright light in the lives of many classmates, always with a smile on his face. She says she was shocked to hear details surrounding Graville's death.

"Had somebody else outside the family known this was going on, could we have stepped in, could we have done something, could we have brought people together to get him help and get him out of there? We'll never know," Schmit says.

Mahoney says he can't release much more information at this point in the investigation on a motive, or details on how Graville was killed.


DANE COUNTY (WKOW) -- Authorities are releasing new information as they continue to investigate the death of a missing Mazomanie man.

Officials say a body was found Monday afternoon in a wooded area near Highway 130 south of Lone Rock. Authorities say the body closely matches the description of 27-year-old Matthew Graville who has been missing since June 30. An autopsy was scheduled for Tuesday.

Officials say three people have been taken into custody, including Graville's stepmother and stepbrother.

The Dane County Sheriff's Office says 27-year-old Jeffrey Vogelsberg is currently being held in the Pierce County Jail on a tentative charge of First Degree Intentional Homicide, for the killing of Matthew Graville, and a felony charge of Hiding a Corpse. Vogelsberg is the half-brother of Matthew and has been living at Fort McChord in Lewis, Washington since late July with his wife who is serving active duty in the military.

Authorities say on Saturday, detectives interviewed Matthew's stepmother, 49-year-old Laura Robar, about her involvement with Matthew's disability support and finances. They also interviewed 28-year-old Robert McCumber who led detectives to the location in Sauk County where the body was found.

Robar is currently being held in the Dane County Jail on charges of Identity Theft and Party to a Crime of Hiding a Corpse.

McCumber is the homeowner and lived at the residence in Mazomanie where Matthew lived with the Vogelsberg family. McCumber was a close friend of Jeffery, and admits to burying the body with Vogelsberg. McCumber is also being held in the Dane County Jail on a felony charge of Hiding a Corpse.

Authorities say through this investigation they learned that Matthew suffered extensive physical and mental abuse while living with Vogelsberg and McCumber.


DANE COUNTY (WKOW) -- Authorities say they believe they found the body of a Mazomanie man who was missing since June.

At a news conference Tuesday morning at the Dane County Courthouse, authorities released information about 27-year-old Matthew Graville.

Based on tips received over the weekend, detectives from Dane and Sauk counties searched an area near the Wisconsin River and found Matthew's body.

Authorities say Matthew's stepmother, half-brother and the owner of the property are in police custody. 

Officials say Graville's half-brother is charged with 1st degree intentional homicide. Matthew's stepmother faces numerous charges, including party to a homicide and fraud. She accessed Matthew's bank accounts and used his food stamps. The landlord is charged with helping conceal a corpse.

According to authorities, Matthew was likely killed July 1. He had not been seen since June 30 and deputies first went public with the case last month. They said Matthew was considered endangered, as he had Asperger's Syndrome.
