An affidavit revealed gruesome details about the death of a father who was allegedly killed by his son in Boonton Township on Christmas Eve.

Gregory Meyer, 61, was found dead inside his residence on Christmas Eve. His 33-year-old son Kyle was arrested and charged with murder, unlawful possession of a weapon and possession of a weapon for an unlawful purpose.

The affidavit revealed Gregory was killed in the basement of his home. The police report says his mother was home at the time and heard her grandson Kyle and her son Gregory arguing in the basement. She then heard screams — and then heard silence.

Gregory's daughter ultimately discovered the disturbing scene and called the police, the affidavit says. A bloody pole saw and axe were found near the body. The report also revealed that blood was found in the basement as well as on the stairs leaving the basement and leading up to Kyle Meyer’s bedroom.

The Meyer family says Kyle suffered from recurring periods of delusions and extreme paranoia. The family posted a statement on a GoFundMe page that was created and said Kyle was "lost in the darkness of mental illness, alcohol and abuse of drugs."

The Meyer family released the following statement:

"Greg was greatly loved by his friends and family and we are grieving his death. Our family believes it lost Greg's son Kyle many years ago when Kyle gave himself over to alcohol and abuse of drugs legal and illegal. That abuse led to recurring periods of delusions and extreme paranoia, making him think others were out to kill him. Greg was a loving father who tried to help. Our family was told Kyle could not be committed against his will unless he made threats---we want to warn other families that mental illness should be taken seriously, and those with delusions of paranoia can be a violent threat waiting to happen."

Police say there’s no threat to the community, and they’re not looking for additional suspects. However, they ask anyone with more information to contact the Morris County Prosecutor’s Office.

A detention hearing for Kyle will be held Thursday at 11 a.m.
