Chester Mass

KENOSHA COUNTY (WITI) — A jury on Wednesday, April 22nd returned a guilty verdict for 39-year-old Chester Mass, charged with first degree intentional homicide and felon in possession of a firearm in connection with a standoff that occurred in Kenosha which resulted in an explosive breach and the discovery of a woman who was shot to death.

Mass admits to shooting Heather Adamski in December 2013, but claims it was an accident. Mass told authorities he and Adamski had sex and were playing with a gun when he accidentally shot her in the head.

According to a criminal complaint, on December 4th, Mass woke his brother, Justin Mass, and told him he shot Adamski. Mass then asked his brother to help him get rid of her body.

Justin Mass said he feared for his safety after allegedly seeing a gun in his brother’s hand. Justin, however, was able to run out of the house and call 911.

Court documents also show Mass told Adamski he had another woman at the house and if she didn’t come home he would throw out her belongings.

Both Adamski’s daughter and a friend told law enforcement she and Mass had a rocky relationship. They also claim Mass made death threats toward Adamski.

In court on Wednesday, April 22nd, a jury found Mass guilty on both charges.

He will be sentenced on June 25th.
