A Murray woman has been charged with attempted murder after allegedly attacking her mother in West Valley City earlier this week.

Dianna Sue Robles, 30, was charged Wednesday in 3rd District Court with the first-degree felony. She was also charged with assault against an officer, a second-degree felony; aggravated assault, a third-degree felony; and misdemeanor counts of burglary of a vehicle and criminal mischief.

On Sunday morning, Robles' mother noticed that her daughter was acting "very strangely," according to the charges. Sometime later, Robles told her mother, "You're not my mom. You're the devil," and stabbed her mother with a knife, shouting "I am going to kill you," according to the charges.

Among her stab wounds, Robles' mother suffered a punctured lung, a nicked aortic sack and a stab wound in her neck that nearly hit an artery.

The mother was able to run back into her home, in the area of 3300 South and Westcrest Road (4250 West), when Robles' attention turned to a neighbor, whom she attacked with a cooking pot lid, the charges state.

When a police officer arrived, Robles was sitting in a car and came out holding a long pipe "in a threatening manner," according to the charges. When she refused to drop the pipe, the officer brandished his firearm and deployed pepper spray. When she kept approaching the officer with the pipe, "in an aggressive manner," the officer then used his Taser, subdued her and took her into custody, the charges state .

Robles' first court appearance is set for Tuesday.

She is being held at the Salt Lake County Jail in lieu of $500,000 bail, cash-only.
