On November 5, 1984, Sandra Marie Armstrong Warren, 46, and her husband James Julian Warren Sr. were murdered in their Rogers, Arkansas home during a violent rampage by William Frank Parker, their former son-in-law. Parker, reportedly armed with a gun, first confronted James and his daughter Cindy outside the house, fired at Cindy and missed, then chased James into the home where he shot and killed both James and Sandra.

The violence continued that day when Parker later located his ex-wife Pam Warren, kidnapped her, and shot her and a police officer. Parker was arrested and convicted in 1985 on multiple counts, including two counts of capital felony murder for Sandra and James Warren; that death sentence was later reversed by the Arkansas Supreme Court on a legal technicality related to a burglary charge. He was retried, and in 1989 a jury again convicted him and the death sentence was reinstated. The case record states Parker planned to kill the entire Warren family.

Did anyone in the Rogers area know the Warrens or the family dynamics that preceded November 5, 1984?
