Authorities identified the shooter as Roberta Esposito, a transgender woman, whose attack killed two members of her own family and left three others critically injured.

Three people, including the suspect, were fatally shot during a Rhode Island youth hockey game Monday, authorities said.

"We have three deceased. The suspect, and then we have two victims, and then we have three at the hospital," said Tina Goncalves, police chief in the Rhode Island community.

The 18-year-old fatally shot her mother and stepbrother as well as six people at a school, before killing herself. Her motive was unclear, but police had visited her home several times for mental health issues.
