A Murphys woman who believed another woman was having an affair with her boyfriend is accused of stabbing her twice in the abdomen during a fight outside the Downtown Plaza Laundromat on Stockton Road Thursday morning.

The victim sustained two non-life threatening puncture wounds from a folding pocket knife, said Sonora Police Department Chief of Police Turu VanderWiel.

The Murphys woman was arrested more than an hour after the fight on suspicion of attempted murder.

“She was verbalizing she was going to kill her while she was actively stabbing her, so we believe that was likely her intent,” VanderWiel said.

A fight broke out at approximately 10 a.m. Thursday. The suspect said there was a prior altercation between her and the victim early in that morning on Stockton Road, VanderWiel said.

“One of the witnesses indicated that the fight broke out at the laundromat, however the exact location is still unclear,” he said.

The fight broke up when a Sonora Police Officer arrived at the scene and the victim did not immediately identify herself as involved, VanderWiel said.

“There were several people in the area and it was hard to figure out who was actually involved because there wasn't too many people willing to give us information about it,” he said. “We did contact both parties on scene, but the victim was fearful of retaliation if she were to talk to us at that point.”

VanderWiel said the victim was wearing “thick clothing,” it was “not obvious” that she sustained stab wounds. The victim left before she was identified as one of the parties involved.

The suspect was identified by the officer on scene but was released because the extent of the altercation was not known at that time, he said.

At about 11 a.m., the Sonora Police Department was contacted by Adventist Health - Sonora that one of the women had checked into the emergency room for treatment of stab wounds.

VanderWiel said an officer confirmed the victim sustained “significant” puncture wounds.

The suspect, Amanda Burback, 28, of Murphys, was contacted at approximately 11:30 a.m. at the Gold Lodge on Stockton Road, where she told an officer she was staying.

Burback was booked into the Tuolumne County Jail on suspicion of attempted murder.

VanderWiel said Burback was charged on suspicion of attempted murder because the victim told an officer that Burback was threatening to kill her during the stabbing.

VanderWiel said an officer was reaching out to other witnesses to corroborate that statement and “other aspects of the altercation as well.”

The knife has not been recovered. VanderWiel declined to give additional information on the knife while officers attempted to locate it.

Burback remained in the custody of the Tuolumne County Jail as of Friday morning and was assigned a bail amount of $500,000.
