Woman To Plead Guilty After Decade-Long Court Battle

TACOMA, Wash. —

After nearly a decade, a Kapowsin mother has finally agreed to plead guilty to helping her son cover up the murder of her daughter-in-law.

Prosecutors said they have always maintained the killing was a conspiracy between mother and son.

Lisa Carlson was found shot to death in the couple's Kapowsin home in July 1998.

Investigators said the crime scene had been set up to appear as though Lisa’s death was the result of a burglary and sex crime.

The mother and son were convicted of conspiring to murder Lisa because she was divorcing Daniel Carlson and threatening to take away their children.

In May 2006, the state appeals court reversed those convictions and the two faced new trials.

Although Carol Carlson, 56, said she is still innocent, she finally agreed to plead guilty to reduced charges of second-degree assault, sexual assault and the violation of human remains.

She must register as a sex offender because of the plea.

Her son, 27-year-old Daniel, still faces murder charges and is expected to plead guilty in January.

Carol Carlson entered what's known as an Alford plea, admitting there is enough evidence to convict her without admitting guilt.

Prosecutors are asking for a sentence of nearly nine years.
