A Kearney woman is in custody following a brutal series of events on Thursday.

According to Kearney Police, Desiree Deherrera went to the home Robert Lester in an attempt to take her 5-year-old son away.

Police say Lester’s daughter, Kristen, and grandson were also in the home.

Lester told police that Deherrera, who was under the influence of methamphetamine, argued with his daughter and eventually began strangling her.

Police say the Kristen was able to escape and lock herself in a bathroom with the child.

At this point, things became especially brutal when Deherrera grabbed a kitchen knife and began stabbing Lester’s german shepherd.  Police say Deherrera thought the dog “was the devil.”

The dog was able to run away but was soon hit by a car, and police say the dog had to be euthanized.

Deherrera was placed under arrest and jailed on charges of felony strangulation, use of a weapon to commit a felony, two counts of 3rd-degree assault and animal cruelty.

Deherrera is being held at the Buffalo County Detention Center.

No other serious injuries were reported.
