Police found the body of Neal's wife, whose name has not been released, concealed in the floor at the shooter's home.
"The shooter took his vehicle and rammed their fence and gate and entered the grounds on foot with a semi-automatic rifle", he added.
Flint said his truck was stolen and his roommate was shot and killed by the alleged shooter whom he described as "Kevin", a known felon in his 50s.
"We don't feel safe", she said tearfully. He said the neighbour "has been shooting lots of bullets lately - hundreds of rounds".
Neal then shot two neighbours in an apparent act of revenge before he went looking for random victims at the community's elementary school and several other locations.
The Rancho Tehama Reserve homeowners' association board was meeting Thursday to talk about more patrols, two days after 44-year-old Kevin Neal killed his wife and four others before he died in a gun battle with deputies.
"We've made it aware that this guy has been insane and he's been threatening us", the man said. "There were screams: a female screaming, a male screaming". Instead, he said Tehama County Sheriff's Department referred complaints to the homeowners' association.
State Sen. Jim Nielsen, a Republican from Gerber, Calif., whose district includes Rancho Tehama, called the incident "senseless violence".
As if that weren't terrifying enough, one of the places he chose to open fire was an elementary school. A second child and a female adult were shot in a truck, authorities said. As he left, he saw a woman lying in the street, apparently dead, with her husband next to her, apparently wounded.
"School staff is commended for their courageous and professional response to this bad incident", the statement read.
"At that time, immediately and without any instruction from law enforcement, our school staff went into lockdown", Fitzpatrick said. When he would call the family in a rage, upset over something, they would tell him to go to a mental health facility and that he needed medication. "I have the right to bear arms, and I will protect my son if I have to".
"Deeply saddened to hear of the shooting in Northern California, the loss of life, including innocent children", Vice President Mike Pence said on Twitter.
Rancho Tehama Reserve, a subdivision that is home to nearly 1,500 people, is described on its website as a "quiet private country community" located 12 miles west of Interstate 5 and about 110 miles northwest of Sacramento. Fitzpatrick also hailed the actions of the school's secretary, who hustled students at the front entrance to safety and stayed in phone contact with the superintendent and monitored classrooms.
