The wife of convicted killer Lyle Menendez slammed the decision to delay a resentencing hearing for her husband and his brother Erik Menendez until late January. “Tomorrow will be the guys’ 35th Thanksgiving in prison. Next month will be their 35th Christmas in prison,” Rebecca Sneed wrote Wednesday on a Facebook page dedicated to Lyle.

Lyle Menendez and his wife, Rebecca Sneed, quietly ended their marriage after more than 21 years together, but she remains a key figure in his life despite rumors of a cheating scandal Sneed says are baseless, PEOPLE has learned.

The couple tied the knot in 2003 while Menendez was serving time for the 1989 murders of his and his brother Erik's parents.
