Two men found stabbed to death in a Scandia neighborhood home on Wednesday were apparently killed by their half-brother, who was arrested in Bonney Lake later that night.

Seth Richard South, 23, of Poulsbo, was charged in Kitsap County Superior Court on Thursday. He faces two counts of second-degree murder, with potential additional penalties due to the crimes being considered domestic violence, as well as an assault charge for hitting a Kitsap County Sheriff's Office detective after he was in custody.

South initially called 911 at 3 p.m. Wednesday, according to charging documents filed in court Thursday, and told a dispatcher that his half-brother had slit his own throat. A 911 dispatcher later told Kistap County Sheriff's detectives that the phone then went silent, and moments later fighting could be heard, and then silence again.

When KCSO deputies arrived at the home on Scandia Road NW, just north of the intersection of Central Valley Road and Highway 308, one man could be seen laying on the floor inside the home, a deputy wrote in an incident report. Deputies entered the home, and one man was found on a kitchen floor, surrounded by blood, with a knife laying next to him.

Deputies, who noted that there were no visible signs of blood elsewhere, such as footprints or fingerprints, proceeded into the home. At the top of a flight of stairs a second man's body was found, and the two were later identified as brothers. The second man, in a seated position next to a chair, also was surrounded by blood and his throat was slit. The report noted a handgun was on a nearby table, with a magazine and bullet next to it, as well as a long rifle in the next room. No one else was found inside the home.

Detectives learned that South lived in the home with the other two men, and was likely driving a black Toyota Tacoma. A grandparent was contacted, who then called South on the phone. According to the report, South told the family member "you're with me or you're against me," and confess to have killed "the boys." A different family member told detectives that South denied killing anyone during a phone call that afternoon, and then a third family member, who also reached South on the phone at around the same time of the 911 call, told detectives that South admitted killing someone but did not say who. In addition, a friend of South's reported to have heard the suspect say he was going to Missouri next.

The warrant for South's arrest and alert for his vehicle was made statewide, and around 8:30 p.m. Kitsap County's CenCom, or 911 dispatch center, was told that Pierce County Sheriff's deputies had South in custody along a highway in Bonney Lake. The Toyota had two flat tires, caused by spike strips placed by law enforcement. KCSO deputies arrived and inspected the truck, and found blood on the center console, gear shift and in the driver's seat, according to charging documents.

South was taken to a Pierce County Sheriff's Office location, where he was interviewed by two KCSO detectives. According to the report, South admitted to have stabbed the victim found in the kitchen, but claimed that man had killed the victim found on the second floor. He then stopped talking to the detectives.

When detectives went to handcuff South, he allegedly "shot forward" into one of them, leaving the detective with a cut on his head.

South is currently in custody at the Kitsap County Jail and scheduled to make an initial court appearance on Thursday afternoon.
