An 18-year-old DeWitt, Iowa, man made a comment to a friend about "stabbing people” the day before Clinton County Sheriff’s deputies found the bodies of his parents Tuesday morning, according to an arrest affidavit released Friday.

Further, Gavin Vaughn William Glasz told the friend “my mom and dad need to be with my grandpa … off this earth,” according to the affidavit.

Glasz made an initial appearance Friday in Clinton County District Court on two counts of first-degree murder in the deaths of Brian Paul Glasz, 51, and Michelle Renee Glasz, 54.

First-degree murder is a Class A felony that carries a mandatory sentence of life in prison without parole. 

He was appointed a public defender and will be back in court Friday, June 23, for a preliminary hearing. Gavin Glasz remained in the Scott County Jail on a $1 million cash-only bond.

Clinton County deputies were dispatched around 9:30 a.m. Tuesday to the Glasz home in the 3700 block of U.S. 30 in rural DeWitt for a welfare check after Brian Glasz had failed to arrive at work. 

According to the arrest affidavit filed in support of the criminal complaint:

Deputies entered the house through an unlocked window after trying unsuccessfully to call the Glaszes on their cellphones and knocking on the door.

While deputies were on scene, Gavin Glasz was outside and came around the corner of the house. While talking to him, deputies noticed that Gavin Glasz had what appeared to be fresh wounds on the knuckles of his hands. He said he was injured when he was punching a punching bag.

He also had a laceration on his right little finger that required stitches. He told deputies that he cut his hand on barbed wire while out for a run.

Gavin Glasz, who was taken into custody on an unrelated warrant, told deputies that he had not seen his mother for four days and last saw his father on the weekend. Deputies who searched him found more than $800 in cash that appeared to have blood on it in his pocket.

Inside the home, deputies saw what looked like a body wrapped in blankets or comforters. They discovered Brian Glasz, whose throat appeared to be cut. The body was found in the laundry room on the main level of the house.

Michelle Glasz also had been wrapped in blankets and was found in a room in the basement. She was cold to the touch and had blood on her.

A man told deputies that he went to the house at 7 a.m. Tuesday to pick up a load of corn to take to ADM. The man said he saw Gavin Glasz in an outbuilding that sits behind the house and Brian Glasz’s truck was inside the building, the man said.

The man further said that he asked Gavin Glasz where his father was and that he replied that he had gotten a ride to work.

Gavin Glasz told deputies he had gone to get food from a fast food restaurant on Monday night and had not been to house for several days.

Deputies searched the house and found a fast food receipt, as well as clothing and footwear belonging to him that had what appeared to be blood on them. Bloody items were found in the kitchen sink, washing machine and other areas.

They also found a bloody footprint in the laundry room near Brian Glasz’s body that was similar to a pair of shoes found in an upstairs bathroom. An empty shoe box for the same type and size of the shoes was found in Gavin Glasz’ bedroom.

A review of surveillance video on the property shows him leaving and entering a rear door of the home several times Tuesday morning. He later is seen wearing different clothes. 

It appeared in the video that Gavin Glasz had dark-colored stains on his light-colored sweatpants. During a search of the house, a pair of light-colored sweatpants with apparent blood stains on the front pant legs was found outside his bedroom in the basement.

The Iowa State Medical Examiner determined that Brian Glasz’s cause of death was from multiple sharp force injuries and strangulation. He also had a blunt force trauma to the head.

Michelle Glasz’s cause of death was strangulation and multiple sharp force injuries.

No 911 calls were made from the home before deputies arrived on scene, according to the affidavit.

On May 28, Gavin Glasz was charged with operating while intoxicated after a traffic stop in the 1300 block of Camanche Avenue in Clinton. He has a pretrial conference June 28 in that case.
