The mother of the 18-year-old student accused of gunning down several people at a Colorado school on Tuesday, killing one, told a reporter she had no idea what prompted her son to commit the violent act.

The New York Post reports that it reached Stephanie Erickson, the mother of shooting suspect Devon Erickson, by phone on Wednesday, but that she was not ready to discuss any details — and broke down in tears.

“We just need a little time right now,” she reportedly said.

Asked if she had any idea what may have motivated her son to open fire at STEM School Highlands Ranch on Wednesday afternoon, the distraught mother had no explanation.

“I don’t, no,” she told the New York Post, while sobbing. “I’m sorry I just can’t talk right now. Thank you.”

Erickson was arrested along with an unidentified juvenile female at the scene on Tuesday. Kendrick Castillo, 18, was fatally shot, reportedly as he rushed one of the shooters in an attempt to stop them. 

Several others were injured in the shooting, and three victims remain in the hospital as of Wednesday afternoon, according to KMGH-TV.

Erickson is due in court at 1:30 p.m. MT on Wednesday, and is expected to face one count of first-degree murder after deliberation along with 29 counts of attempted first-degree murder, according to the news station.

Authorities have not released information regarding a possible motive. CrimeOnline will provide further updates when more information is available.
