A 44-year-old man pleaded guilty to second-degree murder on Friday, admitting he stabbed his mother 18 times in the neck after breaking down her door in a drunken rage in November 2012.
Brodie Lamb, who has schizophrenia with substance-abuse problems, was originally charged with first-degree murder in the death of his mother, 69-year-old Margaret Ryan, inside her White Center apartment. The charge was amended to second-degree murder on Friday, court records show.
The charge also carries a deadly weapon enhancement that will add two years to Lamb’s prison sentence.
With the weapon enhancement, Lamb faces a standard sentence of 14 to 22 years in prison, according to court records. The defense will recommend he be sentenced to 14 years, while the state is to recommend a top-range sentence of 22 years, the records say.
Lamb is scheduled to be sentenced Feb. 20.
Lamb became enraged when his mother refused to let him inside the White Center apartment they shared in the 1300 block of Southwest 100th Street around 5:30 p.m. on Nov. 13, 2012, court records say. He kicked down the door, grabbed a large kitchen knife and repeatedly stabbed his mother in the neck.
In a statement of guilt written by his defense attorney and adopted by Lamb, Lamb said he was off his prescribed psychotropic medications and under the influence of alcohol when he armed himself with a knife and stabbed his mother several times.
