*Update*: Santa Clara County Sheriff's Office have located the red Volkswagon Jetta that investigators believe is associated in the disappearance of missing Morgan Hill teen Sierra Lamar.
The sheriff's office would not say when or where the vehicle was found, or the circumstances that led to its discovery.
"It's still an open investigation," Sgt. Jose Cardoza said. "They don't want to compromise the investigation."
Investigators are still asking to speak with anyone who may have seen the VW Jetta or had contact with the occupants in south County around the time Sierra disappeared on the morning of March 16. She was last seen at her home in unincorporated Morgan Hill, located near Palm and Dougherty avenues.
"They need information from people who saw it just before, during or after," Cardoza said. "They need people to come forward."
Sheriff's Sgt. Jose Cardoza said investigators had focused on the car from witnesses' descriptions and by viewing surveillance video from homes, businesses and buses in Sierra's neighborhood.
The Jetta was seen in the general area of where Sierra lives near Morgan Hill and where her belongings were found after she vanished, said Cardoza, who declined to elaborate.
Her mother, Marlene LaMar, said she last saw Sierra at home about 6 a.m. March 16 before the girl was to leave to catch a bus to school at nearby Palm and Dougherty avenues.
A day later, search teams found her cell phone off the side of the road near Santa Teresa Boulevard and Scheller Avenue, in the opposite direction of the bus stop. The day after that, they found her Juicy Couture-brand purse near Santa Teresa and Laguna Avenue, a short distance from where her phone was found.
Inside were a neatly folded pair of pants, undergarments and gray San Jose Sharks sweatshirt her family believes she may have been wearing the day she disappeared, authorities said.
Also found near the bag were Sierra's schoolbooks, Sheriff Laurie Smith said. The purse and books were "wedged between a building and a big cactus" or bush, Smith said.
Dive teams have searched several reservoirs as well as smaller percolation ponds in the Morgan Hill area.
The sheriff's office also said Monday that an empty handcuff box and used condoms found within 2 miles of the teenager's home were not related to Sierra's disappearance. Investigators had initially thought there might be a connection when the items were found March 29.
