Babysitter charged with killing Wisconsin family’s dog, makes insanity plea: report

A babysitter, who is accused of killing a Wisconsin family’s dog while watching their 4-year-old child, entered a plea of not guilty by reason of insanity Wednesday, FOX 6 reported. 

Kielee Sonnemann, 18, faces one count of mistreatment of animals with the use of a dangerous weapon after the family found their 8-year-old Chihuahua, Batman, with a stab wound to his chest and a plastic bag over his head. 

The criminal complaint obtained by FOX 6 states that a Sussex family hired Sonnemann to babysit their 4-year-old daughter on Jan. 25. When the mother returned home around 9 p.m., the family’s dog was missing.

According to the complaint, the mother said Sonnemann even helped her look for Batman. They searched the house, but they didn’t find him.

On Friday morning, Jan. 26, the family kept searching for Batman, FOX 6 reported, including driving around the neighborhood and reported to the sheriff’s office that the dog was still missing.

The family then called 911 at 1:35 p.m. the same day to respond to the family’s home about an animal complaint, according to the complaint.

The father told investigators that he found the dog hidden beneath blankets in a corner of her bedroom, with “blood all over the place”.

According to the complaint, the father told deputies he suspected Sonnemann, who they’d hired as a babysitter the night before, because she was the only one in the house with their daughter. Sonnemann was also allegedly ignoring the family’s calls, the complaint stated.

At one point, the complaint read that the dog, Sonnemann and the couple’s daughter were all visible in the living room, but said Batman wasn’t visible, and Sonnemann could be seen walking in the hallway where the dog was later found dead.

The family also told deputies a pair of scissors was missing and that they noticed their daughter’s hair had also been cut. 

Deputies said they found a pair of scissors with what appeared to be blood and fur on them inside the top drawer of a dresser in the bedroom.

The court ordered Sonnemann to be evaluated by a doctor and a review hearing has been scheduled for May 6.
