Sussex dog killed, accused babysitter pleads guilty

Kielee Sonnemann, the woman accused of killing a family's dog while babysitting one of their children, appeared in court on Monday, Nov. 25 for a plea/sentencing hearing. 

Sonnemann pleaded guilty. Ultimately, she will spend nine months behind bars and two years on probation. Based on the charges, she faced up to five and half years in prison.

Her attorney told the court that Sonnemann suffers from bipolar disorder that had gone untreated until this crime.

"I loved that dog as my own," Sonnemann said. "It is a horrible thing I’ve done. I don’t know why I did it."

The judge took into consideration Sonnemann’s otherwise clean record, but said taking the life of a beloved family pet requires time behind bars.

The dog’s owners were not happy with the sentence and wanted more jail time.

Case details

Sonnemann, 18, faced one count of mistreatment of animals with the use of a dangerous weapon.

The criminal complaint says a Sussex family hired Sonnemann to babysit their 4-year-old daughter on Thursday night, Jan. 25. When the mother returned home around 9 p.m., the family's 8-year-old Chihuahua, Batman, was missing.

The family told investigators their 11-year-old daughter had just returned from staying at her grandmother's house. The father said 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 wasn't answering the family's calls, they said.
