TUKWILA, Wash. (AP) — Authorities say a 37-year-old Tukwila man is being held on $2 million bail for allegedly killing his cousin and stuffing his remains in a suitcase.

The Seattle Times reports a judge on Saturday found probable cause to hold Rosalio Ramos-Ramos on investigation of murder.

King County prosecutors say formal charges are expected Wednesday.

The King County Medical Examiner's Office hasn't released the victim's identity or cause of death. He is identified as Ramos-Ramos' cousin and roommate in a probable-cause statement outlining the Tukwila Police's case against Ramos-Ramos.

On Jan. 10, the statement says Ramos-Ramos' brother called police and asked them to conduct a welfare check on Ramos-Ramos in their apartment. The officers found him to be "relatively calm."

Documents say the next day, a woman living in the building reported finding human remains in a suitcase that had been left in a covered breezeway.
