A Glenwood, Iowa woman has been arrested for allegedly leaving her three young children in a minivan while she went shopping.

Police say Cindy Zimmerly left her children, ages five, three and one, in the van while she shopped at a Wal-Mart in Council Bluffs on April 27th.

Police say she returned to the van after about 30 minutes, but left again for about 20 minutes. Zimmerly is accused of child endangerment. She was released from jail after posting bond.

She is a special education teacher at Glenwood's Northeast Elementary School. School officials say she's been placed on administrative leave while the district investigates.
