DeLAND, Fla. - The family of a man shot by a Volusia County sheriff's deputy responding to a domestic disturbance call say he was an Army veteran suffering from post-traumatic stress syndrome.

The family of Joshua Gerard released a statement Monday saying he didn't receive adequate treatment for his condition and was "abandoned by the government he so proudly and willingly served." He had been struggling with the condition since his return from a one-year tour in Iraq.

His wife called 911 on Sunday, saying her husband was being violent and doused her in gasoline. She said she saw a deputy shoot her husband as he pointed a shotgun at the officer. Authorities say Gerard refused orders to drop the weapon.

His condition was not released Tuesday.
