BOULDER, Colo. -- It wasn't exactly pistols at 30 paces, but Boulder police say a private security guard and a restaurant owner shot each other with Tasers in a confrontation over parking.

Officers said neither man needed medical attention after the confrontation, but Epstein, a co-owner of Mamacitas restaurant in Boulder, was arrested on suspicion of felony menacing and using a stun gun.

A police report said Epstein and Casey M. Dane, a supervisor for Colorado Security Services Inc., were arguing over a metal boot that one of Dane's guards had clamped on a wheel of a van parked behind Mamacitas.

Dane told police he was afraid Epstein was going to hit him with a 2-foot-long pair of bolt cutters. Epstein told police he had only tried to remove the boot with the bolt cutters and hadn't threatened anyone with them.

Epstein told police Dane put his hand on a holstered pistol and threatened to shoot him. Dane told the Associated Press that he did put his hand on the holstered pistol but never threatened to shoot Epstein with it.

Epstein told the Boulder Daily Camera that Dane menaced Epstein's mother with a stun gun.

"(The guard) pointed a stun gun at my mother's face and I immediately responded with my personal Taser," Epstein told the Daily Camera. "And we shot each other at the same moment."

Both men drew Tasers.

"They shot each other," Police Sgt. Pat Wyton told the Camera newspaper. "It was just kind of a bonehead deal."

The guard claimed the van, owned by a Mamacitas employee, was on property he was hired to patrol. The van owner denied that.
