Monge was last seen at the 24-K nightclub near 14th and Market. Travis Forbes, 31, said he offered her a ride and then dropped her off to get some cigarettes at a gas station at Speer and Pennsylvania.

Forbes works at Deby’s Bakery and Cafe where police issued a search warrant. According to the affidavit, a detective discovered what appeared to be five drops of suspected dried blood on the floor.

The owner of the bakery told CBS4’s Howard Nathan that what really happened was that an employee was carrying a bag filled with blueberries and blueberry juice spilled onto the floor.

The affidavit states surveillance video inside the bakery shows Forbes turning off the video system on the night after Monge went missing. The bakery owner would only say that she knows Forbes did something wrong inside, but it had nothing to do with suspicion that Forbes was getting rid of something connected to Monge.

Monge’s family fears she is being held against her will.

“We know somebody is keeping her from contacting us and want whoever that is to let her call us,” said Monge’s stepfather Tony Lee.

“We need her and she’s the only person I trust; and without her I feel like there’s a whole lot of me missing; and it’s not a regular day for me anymore and the weeks that go by they just don’t feel like weeks, they feel like years and ages and I just need my sister back,” Kimberly Lee said.

The FBI and the Center for Missing and Exploited Children is helping with the search for Monge. Monge’s profile is now posted on the website for the National Center For Missing And Exploited Children (MissingKids.com). She’s one of 27 people from Colorado with a picture on the site.
