A REMORSELESS killer who forced his elderly and frail boyfriend to choke on his dentures during a bout of "rough sex" in a Mayfield boarding house has been jailed until at least 2039.
Zachary Joel Dowling, now 37, a quick-to-anger career criminal with a history of choking older men, was drunk and assaulting his "on-again, off again" boyfriend, 64-year-old Brian O'Sullivan, in his bedroom at the boarding house in Regent Street on the night of June 29, 2021.
