The Rhode Island hockey player whose family was gunned down by his deranged trans father during one of his games last month scored the winning goal to send his team to the championship — as he honored his slain relatives.



Blackstone Valley School’s star captain Colin Dorgan netted the game-winning goal — in double overtime — Wednesday night in Providence before his Beavers teammates mobbed him on the ice, celebrating their berth at the Division II final.



The senior defenseman, wearing a patch on his uniform with the initials of his mother, brother and grandfather, called it “the greatest moment of my life,” according to WPRI.



Dorgan was on the ice at the Dennis M. Lynch Arena in Pawtucket on Feb. 16 when his father, Robert Dorgan, opened fire in the stands, killing his ex-wife, Rhonda Dorgan; their adult son, Aidan Dorgan; and his ex-father-in-law, Gerald Dorgan.



Gerald’s wife, Linda, and family friend Thomas Geruso were both critically wounded in the shooting.

The crazed gunman, who identified as transgender and also went by Roberta Esposito, then turned a gun on himself.

After the shooting, it was revealed that the 56-year-old gunman had recently undergone gender reassignment, and his trans identity and unhinged personality were a source of multiple family court battles leading up to the shooting.

The maniac gunman had also shared surnames with his in-laws because he and his ex-wife, who married in 1992, were first cousins once removed.
