The gang member who stabbed a 15-year-old to death outside Parkdale High School in April pleaded guilty to first-degree murder Tuesday and was sentenced to 30 years in prison.
Eighteen-year-old Rony Antonio Izaguirre-Henriquez got out of a gold Honda and approached Guillermo Medina and two of his friends as they were walking outside Parkdale the afternoon of April 2.
Izaguirre-Henriquez, a member of MS-13, asked Medina “who he was repping,” a demand to know to which gang Medina belonged, said a spokesman for Prince George’s County State’s Attorney Glenn Ivey.
Medina, a member of a rival gang, the Brown Pride Locos, said he didn’t want any trouble. Izaguirre-Henriquez responded by pulling out a butterfly knife and stabbing Medina once in the chest, killing him, prosecutors said.
Izaguirre-Henriquez’s younger brother, Walter, was driving the Honda. He pleaded guilty to second-degree murder last month and was sentenced to five years in prison.
The brazen murder rattled the nearby middle-class neighborhood and put parents on high alert. It was the second deadly incident near a Prince George’s school last year. In January 2008, a 17-year-old girl was shot to death as she walked home from Charles Flowers High School.
Rony Izaguirre-Henriquez spent a week on the run from police and was caught in Fairfax County on April 10. His younger brother was arrested April 4.
At the time, Walter Izaguirre-Henriquez was already wanted on assault charges stemming from a March 14 incident in which he and a group of MS-13 gang members allegedly attacked a Northwestern High School student outside a 7-Eleven in Hyattsville. The charges in that case were later dropped, and the victim survived his injuries.
