Another day of searching for a couple that vanished during a fishing trip on Thanksgiving Day.

Van Chanpenxi, 64, and Chantra Chanpenxi, 51, went to the Delta north of the Rio Vista Bridge, where their boat was later found by the U.S. Coast Guard.  Family members said they haven't heard from them since.

On Monday, the Sacramento Sheriff's Marine Enforcement Detail had two boats on the water and detectives coordinated Search and Rescue teams.  K9’s and volunteers were also used along the shore, and the CHP had a fixed wing overhead to provide assistance from the air.

Authorities also searched the couple's home for possible clues.
