IRWIN (KDKA) – A Westmoreland County woman who disappeared with her two young children has been found safe in South Carolina.

A “Missing and Endangered Persons” alert went out for 22-year-old Champale-Humphrey-Biglow and her two daughters, ages 2 and 4 months.

She took off Monday afternoon from Pennsylvania Avenue in Irwin, and turned off her phone so that she could not be tracked.

Police say Humphrey-Biglow has mental issues and has threatened to take her own life and the lives of the two girls. As a result the “Missing and Endangered Persons” alert was issued for the three of them.

Around 6:30 a.m. Tuesday, an Irwin police officer tried that cell phone number once again and she picked up.

“Champale and the children have been located in South Carolina. We have talked to law enforcement and they are currently staying there right now. We are actively pursuing other avenues as to how we can work this out to get the kids back,” Irwin Officer Bill Sombo said.

Police also want Humphrey-Biglow back so that she can face charges. She had driven more than 500 miles to get to Columbia, South Carolina.

The family had recently moved to Irwin from Colorado and according to police, they have lived in several different places over the years due to the boyfriend’s financial consulting job.

After Humphrey-Biglow was located, police say the boyfriend and father of the girls showed up at the station with paperwork in hand.

“He brought the 302 commitment papers here and we are in the process of taking the steps we have to take to move forward with starting to get the kids back,” Sombo said.

Humphrey-Biglow is with her mother and aunt in South Carolina. According to police, her aunt is a retired police officer.
