West Valley City, UT – The man accused of shooting a city code enforcement officer in the head before dousing her body with gasoline and lighting her on fire said the officer came to his home because he invited her.

“After 40 years of harassment, the b—h got what she deserved,” Kevin Billings, 64, allegedly said after the brutal murder of West Valley Code Enforcement Officer Jill Robinson, according to the Gebhardt Daily.

Robinson, 52, was responsible for looking for violations on homeowners’ properties in the community, such as clutter, abandoned vehicles or overgrowth, the Deseret News reported.

When a violation was spotted, she issued a “courtesy note” to the property owner to notify them of the violation and to request that it be rectified within the coming few weeks.

If the property owner failed to fix the problem after receiving the courtesy note, Robinson would then issue a “notice of violation,” which provided a 10-day window for the owner to get the space into compliance.

“Billings had received several complaints in the mail regarding the condition of his yard and unregistered vehicles on his property," court documents said, according to the Deseret News.

On July 24, he was served with a notice of violation, which gave him until Aug. 6 to fix the problems and to schedule a follow-up inspection.

He was notified that he would be charged $50 per day, beginning on Aug. 7, if he refused to comply.

Billings contacted Robinson on Aug. 8, and scheduled a follow-up meeting with her to take place the next day at 10 a.m.

When she arrived, Billings allegedly shot her in the head, and left her body lying in the driveway next to her Ford F-150 pickup.

A neighbor told police he heard the gunshot, then saw Billings grab a 5-gallon gas can. He poured fuel on Robinson’s body and vehicle, then stood over Robinson “as if he was trying to set her on fire,” according to court documents.

When officers arrived at the scene, they observed burn marks to the lower portion of Robinson’s body, consistent with the neighbor’s account.

The mother-of-four had been with the department for a decade, her family told KSTU.

Billings had allegedly accused his neighbors, Stephanie Sheen and Ryan Luke, of having complained to Robinson about the state of his property, and set fire to their home as well, the Deseret News reported.

Luke, who suffered minor smoke inhalation, told police he was working at his home office when he “heard an explosion and felt the concussion from the blast.”

“Mr. Luke went downstairs and saw thick, black smoke coming through his back window, which had been broken out,” court documents read, according to the Gephardt Daily. “Mr. Luke exited his home and saw that a truck in front of the house of his neighbor, Kevin Wayne Billings, was also on fire, and observed Ms. Robinson’s body in Billings’ driveway.”

The couple’s six dogs and two cats died in the fire, which was ignited on the back deck before it spread to the house, the Deseret News reported.

The home was a total loss.

Investigators discovered a large hole cut in the fence between Luke’s residence and Billing’s property, and recovered over 400 blasting caps and 1,000 yards of detonation cord from Billings’ property.

Billings has been charged with aggravated arson, aggravated murder, desecration of a dead body, arson, five counts of possession of explosive parts, and four counts of aggravated cruelty to animals.

According to KSTU, he pleaded not guilty to all charges on Aug. 24. His next hearing has been scheduled for Sep. 4.
