The man charged with killing five people at the Cascade Mall in Burlington last September was found dead at Snohomish County Jail Sunday evening, reports the Skagit Valley Herald.

Skagit County prosecutor Rich Weyrich told reporters that Arcan Cetin, 20, appeared to have hanged himself in his jail cell.

Cetin faced five aggravated first-degree murder charges for his shooting rampage, which killed three women, one man and one teenage girl. If convicted, Cetin likely would have been sentenced to life in prison.

Weyrich plans to drop the charges, according to the Valley Herald.

The family of one of the victims, Chuck Eagen, the 61-year-old man killed in the shooting, released this statement to the paper:

We’re understandably in shock over this development. Our heart goes out to Mr. Cetin’s family. We pray that the man repented to God before his death. While this event puts to rest our fear of his release, we harbor no ill will towards Mr. Cetin or his family and pray for their comfort as we know all too well the pain of grief. The family wishes to extend our continued thanks to those who responded to this tragedy, especially law enforcement and the Skagit County Prosecutor’s office for their steadfast professionalism and compassion. We are also grateful to all of those in the community whose love has helped see us through the past six months as we grieve and remember Chuck. The family requests privacy as we continue to process this turn of events.
