TALLAHASSEE, Fla. -- A 15-year-old who was grievously wounded in the Florida school shooting has filed notice that he will sue the 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 a teen-aged gunman who killed 17 people and wounded more than a dozen others on Valentine's Day.

Investigators say former student Nikolas Cruz confessed to the shootings following his arrest.

Attorney Alex Arreaza writes that Borges was hit five times, still can't walk and has "a great deal of difficulty performing rudimentary tasks for himself."

Tampa attorney Marc Matthews explained suing a government agency can be more difficult than suing a company or an individual.

“It's not supposed to be necessarily, but it is in the sense that your potential damages are limited in a significant way,” he said. “You can only sue them up to a certain amount, which is up to $200,000 per person.”

In Florida, government agencies have what’s called sovereign immunity. However, if the government agency has its own liability insurance, coverage might go beyond $200,000.

Matthews said people can also file a claims bill, which needs to be approved by the Florida legislature, for more money.

10News reached out to the Broward School District and the sheriff's office. The sheriff's office didn't get back to us. The school district tells us they don't respond to questions about pending litigation, but they do confirm they have liability insurance.
