An 18-year-old changed pleas to guilty Monday in both a robbery and burglary case from this spring.

Kim Monykuany of Austin pleaded guilty to second-degree burglary and simple robbery. Charges for first-degree burglary and felony theft were both dismissed.

In the burglary case, Monykuany left school with another person on April 13 and broke into the victim’s home, as they knew the homeowners’ schedules, according to the court complaint. The victim states that she heard rustling in the house when she came home and then saw that someone left a door open. Monykuany admitted he and the other person broke into the house, intended to take a laptop computer but did not because it was password protected, according to the complaint. Monykuany reportedly stole an iPod instead and sold it for $20 and was supposed to receive marijuana, as well. Police questioned Monykuany about the alleged robbery after they watched him leave school on surveillance that same day.

In the robbery, Monykuany and a group of teens approached a 14-year-old, held him, punched him in the stomach and stole his iPhone on May 27. Police arrested Monykuany at his home, after the victim and his mother told police about the attack.

Monykuany’s sentencing is set for Oct. 19.
