“I knew that he target-practiced and we’d talk about that. He’d go to a rifle range so I knew he had some ammunition,” Eppler said. McKiernan talked about reloading shell casings but said he hadn’t done it in some time, Eppler said. “I’ve been a psych nurse for 30 years and I didn’t notice anything unusual,” the neighbor said. The day after the fire an incongruous scene played out in the windy hilltop neighborhood of older middle-class tract homes set against a backdrop of the snow-capped San Bernardino Mountains – part of a quiet semi-rural community that bills itself as “Horsetown USA.” Riverside County sheriff’s deputies and federal Bureau of Alcohol, Tobacco, Firearms and Explosives agents carried charred boxes and pieces of furniture out of the house, stacked numerous boxes of ammunition in the driveway and examined seized rifles. NORCO – More than a million rounds of ammunition, numerous weapons and a tunnel were found in a man’s home after a fire that exploded bullets and forced a neighborhood evacuation, authorities said Friday. The homeowner was hospitalized for a 72-hour psychological evaluation after being rescued from the house by a neighbor and then struggling with authorities who prevented him from re-entering, but he was not arrested. Gary Eppler, who lives across the street, identified him as Thomas McKiernan, a retired machinist in his 60s who recently separated from his wife, has grown children and didn’t seem unusual in the nine years he has known him. Eppler said McKiernan had an interest in guns and has a son who is an Army sniper who went to Iraq last year and returned safely. Two weapons were assault rifles that were illegal and the man had no permit for 75 pounds of black gunpowder that was found, said sheriff’s Deputy Juan Zamora.160Want local news?Sign up for the Localist and stay informed Something went wrong.
