2nd suspect booked in murder of 82-year-old sex offender

MARYSVILLE, Wash. -- The Marysville Police Department has booked a second suspect in connection with last month's murder of an 82-year-old sex offender in a Marysville trailer park.

According to police, the 26-year-old Marysville man, who was already in Snohomish County Jail for an unrelated charge, helped a woman stab Arthur Schroeder to death Jan. 22.

The man has now been booked for investigation of murder, robbery and theft of a motor vehicle.

The 28-year-old woman, who knew Schroeder through his grandson, was also already in Snohomish County Jail on an unrelated charge. She was booked in connection with the murder on Sunday.

Schroeder's grandson found him dead of stab wounds, his trailer ransacked and his truck stolen last month. His truck was later found on fire.

According to police, Community Transit surveillance footage shows the two suspects getting off the bus outside Schroeder's trailer park on the afternoon of the murder.

Afterward the suspects, wearing bloody clothes and holding a bag of bloody knives, drove to the man's home and told multiple people they stabbed and murdered an old man, according to the police.

Police are still looking for others who drove the suspects around and burned the victim's truck.
