A judge Tuesday set bail at $250,000 for the Tulalip man, 35.
Court records allege he gave a ride to Delaney Wood, 28, the same day Arthur Schroeder was killed in his travel trailer at the Brookside Mobile RV Park in the 9800 block of State Avenue.
Wood, who was a neighbor of the victim, and Robert Ruben Kennedy, 26, were booked into the Snohomish County Jail for investigation of first-degree murder, robbery and motor vehicle theft.
Schroeder, 82, was found Jan. 25 inside his ransacked trailer.
Marysville police arrested the Tulalip man for investigation of witness tampering late Monday night.
Detectives believe the man gave Wood a ride from Everett to Marysville late on the night of the stabbing. Cellphone records show that Wood contacted the man twice that evening.
That night he and Wood allegedly stopped by one of his friend's homes to use her phone. The woman told police she saw Wood in his car and that she was unresponsive with a "freaked-out look like a look of guilt," court papers said.
The man allegedly told his friend that Wood had "spilled her guts" about the homicide, according to court documents.
The woman said the next day he called her to tell her to be quiet about the homicide. He allegedly told her, "Don't say anything. People are going to disappear. You might be the next."
He also allegedly told her police would be asking questions and warned: "Keep your mouth shut if you know what is good for you or you're going to get hurt."
After the stabbing, Wood allegedly bragged about killing a sex offender. Kennedy allegedly told a friend that "things went bad" and he was sorry for what happened, according to one of several search warrants in the case. Kennedy reportedly said he and Wood went to Schroeder's home to get money, but the elderly man didn't want to give them any.
As it turned out, the pair said they only got $200 from the robbery and they split it, according to an acquaintance who spoke with police.
Schroeder's pickup also was missing from his driveway. It was found ablaze on vacant land north of Arlington, hours after the body was discovered.
