ARAPAHOE COUNTY - The 18-year-old woman accused of killing her mother and fleeing the scene appeared in Arapahoe County Court Friday morning.
Isabella Guzman is being held without bond on suspicion of first-degree murder after her mother, Yun-Mi Hoy, was found dead following a "family disturbance."
According to an affidavit, the suspect's father, Ryan Hoy, called police Wednesday night and told them his wife and stepdaughter were inside a bathroom, and he could see blood coming out from underneath the door. He later told officers his wife had been taking a shower when he heard her yell his name.
Hoy said he could not open the door but believed his wife was wounded.

He also said police had visited his home earlier in the day on a welfare check following a fight Guzman had with her mother. Responding officers spoke to the mother and daughter before determining the issues had been resolved.
After telling dispatch this information, he stayed on the phone as he heard the door open. Once the door was open, he said he saw his wife with her throat slit, and his stepdaughter with a knife in her hand. His stepdaughter walked past him and went downstairs.
Guzman went into the backyard, and Hoy attempted to perform CPR on his wife until officers arrived on scene, the affidavit said.
Hoy told police that his stepdaughter had fled. The body of Yun-Mi Hoy was found upstairs in the bathroom with a baseball next to her.
"The officer described it as a pretty gruesome scene," Aurora Police spokesperson Frank Fania said.
Guzman was found by police Thursday afternoon walking out of a parking garage at 2851 South Parker Rd. Police were originally called out earlier in the day on a report of a body inside a car.
When police made it to the scene, they didn't find anyone inside, however they did find items linked to the murder in the car.
"We brought in a K-9 and started to do a search of the parking garage. We believe Ms. Guzman saw this coming and saw the dog doing a search and tried to walk out of the parking garage and ultimately was recognized by some of our officers and taken into custody," Fania explained.
Anyone who has any information on this case is asked to call Detective Mark Yacano at (303)739-6090.
