She is being held on suspicion of child abuse.
Police arrested a 39-year-old Utah woman after she allegedly locked her two young children in the trunk of her car while she shopped at a local Walmart.
Riverdale Police said that they received a call on Thursday after a woman allegedly spotted the mom stuffing the children, ages 2 and 5, inside of the trunk in the store’s parking lot, according to reports.

"The small children ... began making noise and moving frantically, causing the vehicle to shake," Police Lt. Casey Warren told CNN. "Several good Samaritans observed this and came to the aid of the children.”
Another witness, Heidi, told ABC7 that she heard the 5-year-old girl screaming from inside, “Mom, let me out! Help!”
Bystanders reportedly coached the 5-year-old on how to pull the emergency latch from inside the trunk and were able to get the kids out.
"Both kids came out, like, jump spring loaded, they just jumped out at us. One lady took the 2 year old. I took the 5 year old. I was like, 'this can't be what we're finding,'" Heidi said.
Heidi told the station that once police arrived and the mother, Tori Lee Castillo, exited the store, her alleged excuse was that the children’s babysitter didn’t show up.
