JACKSONVILLE, Fla. -- A local mother whose twins died in her arms after being shot in 2015 is suing the United States Navy for $75,000.

In November of 2015, Megan Hiatt, who was 22 at the time, was living with her then-boyfriend, Gawain Wilson, 28, and her 5-month-old twin daughters, Rose and Reese.

Wilson reportedly burst into their Oceanway home and started shooting, according to our news partners, The Florida Times-Union. Police said he struck Hiatt's daughters and forced her to hold them as they died. He also killed Hiatt's father, Travis Hiatt, 49, before he shot and killed himself, police records show.

The lawsuit claims the Navy was negligent in preventing the shooting. It claims the Navy was knowledgeable about Wilson's behavior and his "prior history of committing violence and violent acts against women."

It further suggests that Wilson's co-workers overheard Wilson get into a fight with Hiatt on the phone the day of the shooting while at work; that "Wilson became agitated ... and made threatening and/or violent comments to Hiatt during the same telephone conversation" the day of the shooting.

Hiatt is suing the Navy for $75,000.
