A 64-year-old Chicago woman has been accused of commissioning her teen grandson to kill her husband as he awaited a ride to a dialysis appointment last month.

Janet Strickland was charged with first-degree murder and armed robbery, but was not in court because she is being treated at a hospital for a lung disease, MyFoxChicago.com reports citing a Chicago Sun-Times wire.

Police say two men approached 72-year-old William Strickland Mar. 2 outside his home as he was waiting for a ride to his dialysis treatment and shot him.

Authorities say Janet Strickland gave her 19-year-old grandson, also named William Strickland, her husband's gun, and let the teen use her car the morning of the murder.

Janet Strickland allegedly watched the teen kill his grandfather, and then took him shopping for a new car. The teen also allegedly used money from his grandfather's wallet to buy shoes and tattoos, among other things.

The teenager was charged with murder and is being held without bail.
