BROWNSVILLE, Ore. - Kathy Rocha and Helen Wilkins still get teary eyed when they remember their sister Gerlene Thorne.
"She enjoyed camping, garage selling, being a full-time mother," Wilkins said.
"This is hard," Rocha said. "This is just so hard."
In October 2009, Thorne's son Josh Shaddon murdered her.
"How could he take his mother's life? The only one who loves him?" Rocha said. "He stabbed her in the back, he stabbed her in the chest, she had wound marks on her arms and then he slit her throat."
A court found Shaddon gulity except for insanity on the charge of murder.
Shaddon was placed under the jurisdiction of the psychiatric security review board. He was diagnosed with bipolar disorder and sent to the state hospital in Salem.
The process has meant that even after the trial, the sisters have faced the prospect of hearing after hearing on the fate of their sister's killer.
"It's so hard to heal and let it go because it's always there," Rocha said.
The next hearing is May 7.
"There is a possibility he will be let out," Rocha said.
That's a prospect the sisters oppose.
"My sister would want him to get the help he needed," Wilkins said, "and two years is not going to do it."
