KENT, Wash. — A 24-year-old man convicted of murder in the brutal stabbing of a Des Moines woman has been sentenced to 40 years in prison.
Daniel Alexander Threadgill stomped on Jennifer Walstrand’s head and stabbed her at least 63 times in August 2010, prosecutors said.
A jury convicted Threadgill of first-degree murder in February.
Police said they uncovered Threadgill as the murderer after several cooperating witnesses who were present at the time of the attack came forward.
Investigators said the attack was motivated by jealousy and a dispute over prostitution.
Senior Prosecutor Carla Carlstrom also obtained a guilty finding that the murder was committed with deliberate cruelty.
Because of the brutality of the killing, prosecutors requested an exceptional sentence of 40 years in prison.
The standard sentence range is 22 to 28 ½ years.
During the sentencing at the Regional Justice Center in Kent, Threadgill addressed the court, crying and maintaining innocence.
