A Slidell woman who learned her ex-boyfriend had a new love interest pistol-whipped her rival and fired a shot at her, according to Slidell police officers who arrested her Tuesday night after getting a call that two women were fighting.

Myrna Tegones, 48, was booked on counts of attempted first-degree murder, illegal carrying of a weapon and possession of stolen property, said Sgt. Daniel Seuzeneau, a Slidell Police Department spokesman.

She was being held at the Slidell Jail.

Tegones, who had recently broken up with her boyfriend of several years, became enraged when she learned he was seeing someone else and went to the woman’s home in the 1400 block of 11th Street to confront her, Seuzeneau said.

Police arrived on the scene about 8:30 p.m. and found two women fighting in the front yard, one of them injured. A loaded semi-automatic handgun that appeared to have been fired was on the ground next to them.

Tegones had forced her way into the other woman’s home and began hitting her in the head with the gun, firing a single shot in her direction, Seuzeneau said.

The victim ran outside and began yelling for help, he said. Tegones chased the woman, gun in hand, but the woman was able to knock the weapon out of her hand, Seuzeneau said.

Police arrived shortly thereafter, and the victim was taken to a hospital, where she was treated for moderate injuries.
