A total of four men have now been arrested in connection with last December's murder of 37-year-old Michael Eby and 35-year-old Ryan Pederson.  Their bodies were found in a car near the Roza Canal. Capt. Rod Light says on Friday detectives arrested Marco Gallegos and Heriberto Villa in Yakima making a total of four arrests. Light says detectives believe drugs played a role in the murders.

Gallegos and Villa are both being held on murder and kidnapping charges. Two other suspects have already been charged with murder.
