Detectives say they solved Theresa Still's murder.

Police arrested Still’s live-in boyfriend Greg Gubernot early Friday (1/8) morning and charged him with first degree intentional homicide. A judge set his bond at $1 million.

Eau Claire County District Attorney Rich White says he asked for that amount because of Gubernot's prior abuse cases involving Theresa Still. White also cited part of the criminal complaint that shows Gubernot telling a person that he would leave town.

Investigators say Gubernot murdered Theresa Still and tried to hide her body 100 miles from their Altoona home. An autopsy showed Still was beaten and strangled to death.

Theresa Still's family was in court Friday afternoon. Family members had tears in their eyes as Gubernot sat down at the defendant’s table.

Our sister station, WEAU broke the story of Gubernot's arrest early Friday morning. The Altoona police chief says investigators used credit card records to track him to northeast Wisconsin. They say Gubernot was trying to avoid contact with them.

Altoona Police Officer Scott Kelley says the department determined Gubernot was a suspect Thursday (1/7). He says up until a few days ago, he was cooperating with them so they weren't alarmed when he left the area.

Kelley says Gubernot got a ride from a friend to a home in Minoqua in Oneida County. He wasn’t there, but investigators interviewed witnesses that led them to another friend’s home near Crandon in Forest County. Kelley says once Gubernot’s friends learned why they were looking for him, they were cooperative. The Forest County SWAT team helped officers arrest him there without incident.

Officer Kelley says officers with the Altoona Police Department, along with deputies from the Adams County Sheriff's Department and State Department of Justice agents helped track him down.

Officers say Gubernot did not pose a danger to them when they went in to arrest him. Kelley says he does not know if Gubernot confessed to the murder or if he had any plans of heading out of the country.

Officers pulled up to the Eau Claire County jail on Friday afternoon with Greg Gubernot in the backseat, hidden behind tinted windows. After close to two weeks of investigation, White filed murder charges against Gubernot before he was even back in Eau Claire County.

White filed the lengthy criminal complaint Thursday night. It was sealed until Friday morning. The complaint details the investigation from start to finish. It reveals voice-mail messages Gubernot left Theresa Still the last night anyone saw her alive. It also tells us more about the way she died.

"This was a tragically, horrible situation," White tells us. "To have all this (investigative work) done here in slightly over a week is quite extraordinary."

According to the criminal complaint, on Sunday, December 27, the last night Theresa Still was seen alive, a man talked to Gubernot on the phone. He told investigators Gubernot told him Still "wanted him out of the house... 'but I won't have to worry about that anymore.'"
