A Wisconsin mother pleaded "no contest to felony negligence" in the death of son, 16-month-old Tanner, who was left in a hot trailer according to the Star Tribune.
Police found the young mother, Brandie Nelson, trying to revive her song in a trailer at a park in Prairie du Sac last summer, the Chicago Tribune reported.
After being rushed to Sauk Prairie Memorial Hospital, the child was pronounced dead, the Star Tribune said. Nelson faces up to 25 years in prison if charged as guilty.
Nelson told police that she left her son in the trailer with the air conditioning on. She said she checked in on him every half hour. Investigators told the Chicago Tribune that "even with the air conditioning on, the day was so hot the interior would have reached more than 110 degrees."
