A 21-year-old woman accused of stabbing her mother to death last year during an argument over living arrangements pleaded guilty Wednesday.
Laura Jennette Jonston pleaded guilty to one count of second-degree murder with a knife, Pierce County Deputy Prosecutor Phil Sorensen said. She faces 12 to 20 years in prison when she’s sentenced Aug. 19.
Prosecutors said Jonston stabbed her 60-year-old mother, Shirley Miluk, at least nine times on Feb. 20, 2009, in Miluk’s apartment on 153rd Avenue Court East.
Miluk was found after another daughter asked Sumner police to check on her welfare. Officers tracked down Jonston, who had lived in Miluk’s apartment with her young child, court documents state.

Jonston told investigators she and her mother had argued after Miluk decided to kick Jonston out. The argument turned physical.
Jonston said her mother attacked her with a lamp, jar and decorative rooster. Jonston said she stabbed her mother once, then the argument subsided and the two hugged.
The argument later heated up again and Jonston stabbed her mother again, court documents state.
