Police arrested a fourth suspect Monday after five people were killed over the weekend on the Yakama Indian Reservation in Washington state, authorities said.
James Cloud, 35, was taken into custody with the help of a police dog near the town of Wapato after a brief fight with law enforcement officers, the Yakima County Sheriff’s Office said.
Cloud was treated at a hospital for minor injuries and then booked into jail on a federal warrant for aggravated assault.
“Currently there are no further suspects or persons of interest outstanding,” the sheriff’s office said.
The identities of the victims, how they were killed, and a motive were not immediately released.
All the victims were adults, and officials were trying to determine if they were related, Sheriff Robert Udell told The Associated Press.
Some were known to law enforcement for being involved in illegal drug activities, the sheriff said.
Four victims were killed at one location and another was found dead in a vehicle at another site.
More details were expected to be released later in the day by the FBI, which is leading the investigation.
The killings occurred late Saturday near the reservation community of White Swan, about 150 miles (241 kilometers) southeast of Seattle.
Three people were initially arrested. Their identities have not been released.
“I’ve been here 30 years and I don’t remember another case with five different homicides,” Udell said.
The Yakima County Sheriff’s Office, Yakama Nation Tribal Police and the FBI are jointly investigating the killings.
