Survivors of the Gilroy Garlic Festival shooting are filing a lawsuit, claiming there were major lapses in security at the July festival that led to the deaths of three people.

The lawsuit targets the Gilroy Garlic Festival Association. It alleges negligent security measures led to the deaths and injuries from that shooting on July 28.

According to police, the shooting took place on the north side of the festival and the closest team of officers responded immediately when calls came in around 5:40 p.m. about shots fired.

They were there and engaged with the 19-year-old gunman, who was armed with an assault-type rifle, in less than a minute.

Three people were killed in the attack - a 6-year-old, a 13-year-old and a 25-year-old. Why the suspect opened fire still remains a mystery.
