Survivors in Rhode Island hockey game shooting 'fighting for their lives' after gunman kills ex-wife, son

Two people wounded by a gunman during a deadly shooting at a Rhode Island ince rink were in critical condition Tuesday and were "fighting for their lives," Fox News has learned. 

A family contact told Fox News that Robert Dorgan, 56, who identified as transgender and had a history of past family conflict over his gender identity, shot and killed his ex-wife Rhonda and his son Aidan, before shooting his in-laws.

The gunfire erupted Monday afternoon at a high school hockey game at the Dennis M Lynch Arena in Pawtucket.
