(USA TODAY) — The lawyer for a Florida teen shot five times in the bloody rampage at Marjory Stoneman Douglas High School has given notice of what would be the first lawsuit filed against Broward County officials stemming from the Feb. 14 tragedy.

Anthony Borges, 15, was hailed a hero by classmates who said he was attempting to close and lock their classroom door when he was shot twice in the torso and three times in the legs. Seventeen teachers, staff and students died in the carnage.

“The failure of Broward County Public Schools, and of the principal and school resource officer to adequately protect students, and in particular our client, from life-threatening harm were unreasonable, callous and negligent,” attorney Alex Arreaza says in the letter. “Such action or inaction led to the personal injuries sustained by my client.”
