A Virginia teen is critically injured and facing murder charges after authorities say he fatally shot a husband and wife in their home on Friday before turning the gun on himself.

According to WRC-TV, the unnamed 17-year-old boy knew the victims, 48-year-old Scott Fricker and 43-year-old Buckley Kuhn-Fricker, prior to the shooting.

Reports suggest he was dating their 16-year-old daughter and shot them when they confronted him over some issue. The couple had reportedly expressed concern about the suspect’s prior infatuation, if not alignment, with Nazi ideology.

The shooting occurred inside of the Fricker’s Fairfax County home as four other family members were also inside. Those occupants were not injured, WTTG reported.

Buckley Kuhn-Fricker’s mother, Janet Kuhn, described the victims as “a wonderful couple.”

She explained the issues they had been having with the suspect.

“My daughter and her husband found out about a lot of the Nazi stuff just this past week and they forbid their daughter to see him again,” she said.

Kuhn said the final Facebook status her daughter posted was a direct reference to her growing concern about the teen.

“The only thing necessary for the triumph of evil is for good men to do nothing,” Kuhn-Fricker reportedly wrote hours before she was killed.

The Washington Post reported that she recently alerted the school attended by her daughter and the suspect of the disturbing, intolerant images and messages she believed to be linked to the suspect’s social media account.

According to police, the self-inflicted gunshot left the suspect with life-threatening injuries. As of the latest reports available, he remained hospitalized in police custody.

He has not been officially notified of the criminal charges being sought against him due to the severity of his injuries.
