A Reno teen admitted to 911 dispatchers that she shot her younger brother and father at an apartment in Stead on Friday afternoon, court documents obtained by News 4-Fox 11 reveal.

According to the documents, Mashenka Reid, 17, told dispatchers she killed her relatives because she "couldn't control the urge to kill somebody."

Police responded to an apartment at 9755 Silver Sky Parkway just after 4 p.m. on Feb. 9 after neighbors heard arguing followed by gunshots.

Reid called 911 and told the dispatcher, "I shot my dad. I shot my brother. My brother is dead." The teen proceeded to tell emergency responders she dropped the Walther PPS gun inside the house.

When police arrived on scene, they found Mashenka's younger brother - approximately four or five years old - with a gunshot wound to the head. Mashenka was able to direct officers to the garage, where her father was found suffering from gunshot wounds to the chest and back.

Reid also told dispatchers her younger sister was in another bedroom and she "believed she was alive." Police did not release any additional information about the sibling.

Reno Police took her to the police station for questioning but she did not answer further questions to officers. Still, police wrote in the probable cause affidavit that she admitted to dispatchers that she shot her father and her brother, had intimate knowledge of the crime scene, and knew where the gun was located.

The teen is being charged with two counts of open murder with a deadly weapon and one count of attempted murder with a deadly weapon.

Reid is due to appear in front of a judge for the first time on Thursday afternoon.
