DRAPER — A Draper woman was arrested over the weekend after police say she stabbed an ex-girlfriend and the woman’s new partner multiple times before attempting to burn their home.

Adam Jiang Tien, 27, was booked into the Salt Lake County Jail on Sunday for investigation of two counts of attempted murder and aggravated arson.

One of the victims was Tien’s ex-girlfriend, whom she lived with, according to police. Tien became upset when she learned her ex was having a relationship with another woman, according to a police affidavit, and she attacked them both with a knife.

“Officers described the bedroom the victims were in as a bloody scene. There was blood on the walls, on the floor, and everywhere between the bedroom and the front door,” the affidavit states.

Both victims were treated for numerous defensive wounds on their hands and bodies, according to the affidavit. Tien was also treated for cuts on her hands before being booked into jail.

The two victims told police that after being attacked, they locked themselves in a bedroom when “the smoke alarm was going off and they believed Adam was trying to set the house on fire with a blow torch,” according to the affidavit.

Detectives serving a search warrant on the home found a blow torch and “portions of the home which were black from being burned.”

When interviewed by police, Tien “admitted to having a plan and a desire to kill” both women, the affidavit states.

“She said she wanted revenge and went forward with her plan to stab (the women) and burn down the house with them inside,” according to the affidavit. “Adam showed no remorse for her actions. Adam wanted to kill” the two women and the officer wrote that “if Adam is released she will attempt to finish what she started.”
