One of the three suspects in a pharmacy robbery that led to the death of an 86-year-old woman has been arrested.

The robbery happened at the Rite Aid on Auburn Blvd. just before 6 p.m. Monday.

When officers arrived, they learned that three people walked into the store jumped over the pharmacy counter, demanding drugs from the employees.

Fearing for their lives, the employees handed over an unknown amount of prescription drugs.

The suspects ran out of the store, knocking an 86-year-old woman, Marilyn Stribley, who was walking into the store, to the ground. She was knocked unconscious when she hit the ground.

When first responders arrived Stribley did not have a pulse, but officers and fire officials began CPR and other life-saving measures. She was taken to a local area hospital in critical condition where she passed away just days after her 87th birthday.

With the public's help, officers were able to identify the suspect who knocked Stribley to the ground as 21-year-old Kimani Randolph. He was on probation for being a convicted felon in possession of a firearm when the robbery occurred.

US Marshals located Randolph in Las Vegas where he was arrested Thursday. He will be extradited back to Sacramento next week. He is facing charged for robbery and violation of probation as well as additional charges stemming from the death of Mrs. Stribley.

Police are still searching for the other two suspects.
