LAKEWOOD, Colo. — Madison McKindle has been missing since Thursday and her father, Ian, thinks she is in serious danger.

The Lakewood Police Department is investigating the case, but at this point will only call it a runaway and not a missing person.

Ian McKindle admits his 15-year-old daughter has run off before.

“Initially, I thought she was going to blow off some steam because she had done it many times before if we got into a little argument,” he said. “But a couple hours went by and that was longer than usual.”

Madison didn’t come home that night and then her father received a phone call the next evening.

“She said, ‘Daddy I want to come home. Please come get me,’” McKindle said.

Madison was calling, using a passerby’s cellphone in a park near Federal Boulevard in Denver. McKindle told her to wait inside the nearby 7-Eleven on Federal and West Kentucky Avenue, and he left work and got there as quickly as he could.

McKindle missed her by about 10 minutes, and video surveillance from the store shows what happened.

“This guy walked past her, turned around and looked like he said two words to her,” McKindle said. “And these two words were enough to make her get in the car.”

Madison hasn’t been seen or heard from since then. While police still consider the case a runaway, McKindle is pleading for help on social media.

“My phone pretty much dings all night and I just try to answer as many people as I can,” he said. “Try to vet out what’s her and what’s not.”

McKindle said his daughter has had no communication with any friends or family since Friday night, and he’ll do whatever it takes to bring her home.

“I’d do anything for her,” McKindle said. “Just come home. I love you.”

The organization Missing Angels is helping McKindle find Madison and has alerted the National Center for Missing and Exploited Children to the case.
