A Covington man allegedly shot and killed his stepfather following a domestic dispute Saturday evening, according to the Newton County Sheriff's Office.

 Christopher Masiello, 30, was arrested and charged with murder, aggravated assault, firearm discharge while under the influence of alcohol and firearm or knife possession during a crime, according to a NCSO incident report.

 Masiello allegedly became embroiled in an argument with stepfather Paul Larson, 56, shortly before 9 p.m. Saturday at their residence on Island Shoals Road. According to reports, Masiello was under the influence of alcohol and marijuana when he shot Larson several times.

A family member called 911, but the victim was dead from his wounds when the medical first responders arrived, according to the incident report. Masiello was arrested without incident at the scene of the crime.

Investigations are still ongoing and the cause of the dispute is not known, according to Capt. Doug Kitchens of the Criminal Investigations Division of the NCSO. Larson and Masiello reportedly had disagreements in the past but had been getting along recently, Kitchens said.

Sheriff reports said Masiello was disabled and unemployed. Capt. Mark Thomas said the suspect had "mental issues" which contributed to some previous run-ins with the law. "We've had several run-ins with him before," Thomas said.

He was arrested in 2003 for public drunkenness and, in March of 2006, was arrested and charged with arson, battery, criminal damage to property, criminal activity and theft, interference with government property, obstruction and assault. He was bonded out after three days.

The reports also listed Larson and Masiello as having the same address. Masiello had his first appearance Monday in front of Judge Henry Baker. No bond was set for Masiello.

Larson's murder is the sixth this year in the county. Thomas said it was unusual for the area to have multiple murders in less than a month's time.
