A Washington man has been accused of killing his two half-brothers before being arrested on his way to murder a third brother.

Seth South, 23, was arrested Wednesday night, hours after officers found his teenage brothers, Sebastian and Scotty Bass, with their throats slit and in pools of blood inside their family’s Poulsbo home, Kitsap reports Daily News.

Officers found the two victims inside their Poulsbo home with their throats slit and in a pool of blood.

Detectives later discovered that South lived in the home with the two teens, but was nowhere to be found.

Officers then interviewed family members, and South’s grandfather said he told him, “You’re either with me or against me,” and that he killed “the boys.”

His mother also claimed that South told her that he didn’t “hurt the boys,” but her husband, Christopher Bass, claimed that South told him that he killed two people.

The documents also say South told a friend he was going to Missouri to murder another brother, KIRO reports.

Authorities subsequently issued an arrest warrant for South and a statewide alert about his Toyota Tacoma was issued.
