Belanger is charged with murder in the stabbing death of Bonnie MacKay-Belanger in her Chester home on Feb. 25. Police say she called to report he was breaking in, and allegedly named him as the attacker as she was dying.
She had a protective order in place against him and they had been in divorce proceedings since December.
John Belanger returns to court March 29. Public defender James McKay asked for a competency evaluation for Belanger, saying he has mental health issues.
