Four days after a Fairfield woman was arrested in connection to the death of her husband, police revealed that she watched him "bleed out."
Carissa Anne Aldrich’s 10-year-old son stabbed his stepfather, Tim Michael Aldrich, killing him during a domestic violence incident Oct. 25, according to police.
"We have no doubt the boy did it," Lt. Kevin Carella told NBC Bay Area Tuesday. "It’s what transpired [in] the next six hours – steps a reasonable person should have made weren’t made."
Police say the 38-year-old woman was being beaten by Tim Aldrich, 45, when her son, fearing for his mother’s safety, went into the kitchen, grabbed a knife and struck his stepfather.
However, Carissa Aldrich did not call 911 until the next morning, police said, when she realized her husband was not waking up.
Carella said the suspect's actions raise the question of "culpability."
"I don't think a 10-year-old is capable of committing that kind of crime," he said. "There's only two people now that know what happened in that house – the boy and the mom."
At 11:40 p.m. Friday, Major Crimes Detectives took Carissa Aldrich into custody, charging her with involuntary manslaughter, child endangerment and destruction of evidence.
A friend reportedly bailed Carissa Aldrich out of the Solano County Jail. Aldrich is scheduled to be arraigned Dec. 4, according to the district attorney's office.
Meanwhile, charges have not been filed against the boy, who was placed into protective custody with Children’s Protective Services at the time of his mother’s arrest. The child has reportedly been placed with his grandmother.
