Murder charges have been filed against three relatives of an abused Des Peres woman whose husband was shot to death. Lois Sexton had told family members that her husband, Jeffrey Sexton, had been abusing her. Police say the woman’s father, brother, and brother-in-law then plotted to kill Jeffrey Sexton – a union machine operator with a history of drug abuse. Investigators say the three suspects have admitted to their roles in the conspiracy to kill Sexton and have been charged with first-degree murder and armed criminal action. The widow, Lois, Sexton, has not been charged. Police had visited the Sexton home on several occations, responding to domestic disturbance calls.
