Brandon Suhr Killed Girlfriend's 13-Year-Old Brother, Police Say

A teenager who goes by the name "Master Dante 666" online is accused of killing his girlfriend's 13-year-old brother.

At around 3 a.m. on Friday, police in Pacific, Wash. responded to a call from a local man saying that his 16-year-old daughter and 13-year-old son were missing, according to the Daily Mail.

Police searched the man's apartment and found the 13-year-old stabbed to death inside one of the bedrooms, according to Kiro TV. The death was ruled "homicidal violence," and the father is not considered a suspect.

The daughter was not in the apartment, but police ultimately located her, alive but with minor injuries, at the apartment of her boyfriend, 19-year-old Brandon Suhr. Officers arrested Suhr on charges of murder, kidnapping and burglary, according to Komo News. Authorities are not revealing why Suhr is a suspect.

This is not the first time the 19-year-old has had trouble with the law. KBOI 2 reported that Suhr was arrested last month on charges of disorderly conduct, threats to do harm and displaying a weapon. A local family then filed a no contact order on the teenager, stating that he was a violent influence on their son with an unhealthy interest in swords and snakes.

Suhr, whose online identities include "Master Dante 666" and "Dante the Wicked," posted a "License to Kill" certificate on his Facebook page on May 29. The post's caption reads, "Got it to day (sic) so don't fuck with me bitches." The page also lists one of his favorite quotations as, "The blood of the living makes good fertilizer for the seeds of the new." The quotation comes from Conrad Robury's Black Book of Satan.

Suhr's bail has been set at $1 million. He is currently the only suspect in the murder.
