By Associated Press and Daily Mail Reporter PUBLISHED: 17:43 EST, 18 April 2013 | UPDATED: 19:17 EST, 18 April 2013 A 75-year-old Detroit-area woman convicted of murder in the fatal shooting of her teen grandson was sentenced to at least 22 years in prison Thursday, despite her desperate plea to a judge to spare her from dying behind bars. Sandra Layne got a minimum sentence of 20 years for second-degree murder, along with a mandatory two-year sentence for using a gun to kill 17-year-old Jonathan Hoffman. Hoffman was shot six times, including twice in the back, last spring in Oakland County's West Bloomfield Township. Layne said she shot him out of fear during a physical altercation, but a jury in March rejected her claim of self-defense.
