The 19-year-old was in the area of 14th and Market Streets on April 1 when she and her friends lost contact. She was seen a short time later at the Conoco gas station nearby, and hasn't been heard from since.
"It's just been hard for us, so hard," said her mother, Maria Lee. "Somebody has to know something."
Denver Police say this is one of their "top priority" cases, and the family is so convinced that somebody knows what happened to Kenia Monge that they are asking the community to help.
On Sunday, folks gathered at the Royal Gorge Tavern in Greenwood Village for a fundraiser with the goal of adding to the $2,000 Crime Stoppers reward. The hope, family members say, is to get somebody in the community to say what they know, even if that takes some extra money.
"I beg people: please, if somebody knows something about my baby girl to call us," said Lee.
Samantha Ramage is one of many who heard about the case and did something to help. Ramage had never met the 19-year-old. But a friend of hers went missing more than 10 years ago. So she connected with the family on Facebook and organized the Sunday fundraiser, which included a silent auction.
"I just hope that Tony and Maria finally find the answers that they're looking for," said Ramage, as her eyes welled with tears. "And they get to bring Kenia home," she added.
The last person known to have seen Kenia Monge is Travis Forbes. He told 9News that he saw Monge drunk outside a bar and he offered to give her a ride home. When he drove by the Conoco along Speer Boulevard to try to buy cigarettes, Forbes says Monges got out of the van and bummed a cigarette off another man. That was the last Forbes saw of the teenager, he says.
He denies doing anything to her.
Police have never called him a suspect, but he has called himself the main suspect in this case.
Monge's family says they don't know what happened that night, but they're worried because they've heard Forbes is no longer behind bars after being extradited from Texas on an auto theft charge.
