A Long Beach woman who fatally stabbed her caregiver in 2018 was sentenced Thursday to five years in state prison, according to the Los Angeles County District Attorney’s Office.

Theresa Dargan, now 58, pleaded not guilty to one count of murder in 2018, court records show. The charges were changed the following year to involuntary manslaughter.

Last month, a jury reached a guilty verdict following a lengthy trial, according to court records.

Dargan had been arrested four years ago in connection to the murder of her caregiver, 51-year-old Long Beach resident Olympia Riley. On April 14, 2018, Long Beach police arrived at an apartment in the 1400 block of Walnut Avenue around 3 a.m. to assist firefighters with an unresponsive woman who died after being stabbed in the lower body. The cause of the death was listed as a sharp force injury to the leg, according to the Los Angeles County Coroner’s Office.

Long Beach detectives arrested Dargan the following month, with her bail set at $2.02 million.

Police did not publicly release a motive for the stabbing.
