AMARILLO, TX - The mugging of an elderly Amarillo woman turns into murder and police think the person to blame could do it to someone else.
83-year-old Dorcie Plumlee was the victim of a robbery that turned deadly back in October of 2009.
Investigators tell NewsChannel 10, Plumlee was running errands at the Amigos United store off I-40 when someone knocked her down on the ground and took off with her purse. The great-grandmother suffered from a broken hip and shoulder in the attack. Those injuries sparked infections which caused Plumlee's organs to shut down.
Her family decided not to have doctors operate because she asked to them to let her go.
"I thought, she's been through so much, how can we put her through this?' That's a decision, I hope no one has to make, because that is a final decision you are making for them." said Connie Elmore, the victim's daughter.
11 days after her attack, Plumlee died. According to police, the person who mugged her is wanted for murder, but investigators have no idea who that is.
"This is your grandmother who was out shopping. She didn't deserve to get knocked down. If they did that to her, they'll do that to another grandmother...they just don't care." said Lt. Gary Trupe with Potter-Randall Special Crimes.
