• Anthony Borges, 15, is suing the Broward County sheriff's office, school district, and the principal and resource officer at Marjory Stoneman Douglas High 
• Borges is the first student to file a lawsuit over the Valentine's Day shooting that left 17 dead and dozens injured
• In his two-page notice filed Monday, Borges' attorney writes that the school district and sheriff's office could have done more to prevent the shooting
• Borges was struck five times trying to protect 20 other students 
• He continues to recover from his injuries in the hospital and has not been able to walk yet  

A 15-year-old who was grievously wounded in the Florida school shooting has filed notice that he will sue authorities to seek money to cover the cost of his recovery.

A lawyer for Anthony Borges and his family says the sheriff's office, the school resource officer, the Broward County school system and the principal at Marjory Stoneman Douglas High School failed to protect students from the teen gunman who killed 17 people and wounded more than a dozen others on Valentine's Day.

'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 wrote in the lawsuit notice on Monday. 'Such action or inaction led to the personal injuries sustained by my client.' 

The lawsuit is likely to be the first of many filed by survivors and victims' families.
