Authorities say one person has been killed and three others wounded in a shooting during a packed beach party on the Texas Gulf Coast.

Brazoria County Sheriff Charles Wagner told The Facts newspaper that he had no immediate identification of those involved in the shooting at Surfside Beach and no immediate arrests had been made. Wagner says the circumstances were unclear.

The Facts said word of mouth about an unauthorized beach party spread on social media, drawing thousands to Surfside Beach, about 40 miles south of Galveston. Surfside Beach officials told The Facts that the party was not permitted nor authorized.

The Facts quoted a witness as saying the party began peacefully, but fights broke out and there was heavy drinking and also drug use.
