DENVER (CBS/KCNC/AP) - Investigators are searching outside of Denver and around nearby landfills for 19-year-old Kenia Monge, who has been missing since early April 2 in a downtown Denver nightclub.
According to ABC News, dozens of officers conducted interviews over the weekend and searched for clues both in and outside of Denver, including near a landfill in Weld County.
Monge, of Aurora, Colo., disappeared after a night of drinking in Denver. She was last seen at about 12:30 a.m.
Witnesses told police that Monge left her cell phone and purse on a table before walking away to use the club's restroom.
Police spokesman Matt Murray said Thursday the disappearance is not a standard missing-person case. He wouldn't give details, saying the investigation is continuing.
He says the FBI Safe Streets Task Force and experts from the National Center for Missing and Exploited Children are helping with the investigation.
A spokesman for the Denver Police Department said there was a possible sighting of Monge at a gas station at approximately 3:00 a.m. Saturday.
Police spokesman Sunny Jackson said that a man, whom he did not identify, claims to have offered Monge a ride home. The man told police that when he stopped at a gas station to buy cigarettes, Monge walked away with a different man, FOXNews.com is reporting.
Monge is described as Hispanic, 4-foot-11-inches tall, with brown hair and brown eyes. She weighs 115 pounds.
