RANCHO TEHAMA RESERVE, Calif. — A day after a California gunman killed five people in the country’s latest shooting rampage, police faced accusations of having previously turned a blind eye to the troubled shooter who was known for firing off guns despite a court order that barred him from owning firearms.

At a tense news conference Wednesday, police conceded that neighbors had repeatedly complained about Kevin Janson Neal firing hundreds of rounds from his house.

Tehama County Assistant Sheriff Phil Johnston said authorities responded to calls several times, but the 44-year-old Neal wouldn’t open the door, so they left.

“He was not law enforcement friendly. He would not come to the door,” Johnston said. “You have to understand we can’t anticipate what people are going to do. We don’t have a crystal ball.”

Asked about Neal’s motive, Johnston responded: “Madman on the loose. The case is remarkably clear. We will move forward and we will start the healing process.”

The evidence that emerged Wednesday, however, along with residents’ statements raised questions about whether lawlessness was occasionally tolerated.

Neal was also known to have violent squabbles with his neighbors and his wife, both of whom were among his first victims Tuesday.

Police found the bullet-riddled body of Neal’s wife stuffed under the floorboards of their home in the rural community of Rancho Tehama Reserve. They believe her slaying was the start of the rampage.

“We are confident that he murdered her,” Johnson said.

Neal then shot two of his neighbors in an apparent act of revenge before he went looking for random victims, ultimately killing a total of five people, all adults, and wounding 10 at different locations that included the community’s elementary school.

At the time of the attack, Neal was out of custody on bail after being charged in January with stabbing one of the neighbors he later killed in the rampage.

After the January assault, a judge barred Neal from having guns, according to court records. The records also show that Neal was charged with illegally firing a weapon and possessing an illegal assault rifle on Jan. 31.
