A grand jury has indicted a Maine teenager for allegedly killing his parents on Halloween in 2016. He is being treated as an adult in the court system.

The Bangor Daily News reports that the indictment of alleged murder suspect, Andrew Balcer, came on Friday, December 22, who was one month away of turning 18, when he killed his parents and the family dog in their Winthrop home.

Balcer, who is now 19-years-old is being charged on two counts of knowing, or intentional, murder in the deaths of his father Antonio Balcer and his mother Alice Balcer.

He is also being charged with one count of aggravated cruelty to an animal.

Balcer's attorney said that he was having gender identity issues and didn't think that his parents would accept him, so he killed them.
