The City of Jacksonville responded to a lawsuit filed by the family of a man who died while in police custody Thursday.

The suit calls on the Jacksonville Sheriff's Office to give more training to officers when dealing with mentally ill patients.

December of last year, Paul Testa died after being struck with a stun gun during a scuffle with officers.

In a court document filed Thursday, the city says there's no evidence to hold the city liable for the man's death.
