MISSOULA, Mont. -

NBC Montana has obtained surveillance photos showing a woman leaving an Anaconda hospital in June after she and her baby tested positive for methamphetamine.

Authorities say 29-year-old Michelle Renee Yallup left Community Hospital in Anaconda after giving birth.

Anaconda Police Chief Tim Barkell tells NBC Montana that the photos show an SUV Yallup left the hospital in, and other photos show Yallup in a wheelchair and her sister pushing her. Later photos apparently show Yallup emerging from the hospital and apparently leaving in the SUV.

Yallup faces a charge of child endangerment. Authorities say Yallup had been told she was able to leave, but not with the infant.

Yallup was arrested July 21 at a truck stop in Willard, Utah, roughly 50 miles outside of Salt Lake City. She had been on the loose more than a month.

Authorities say the baby is safe.

NBC Montana attempted to contact Community Hospital staff for comment on this story but we have not heard back.
