Shaniqua ’Nikki’ Shavell Wallace was 44 when she was shot and killed at her Abilene, Texas, apartment on November 1, 2018. The woman identified as the shooter was her girlfriend, Lonisha Nicole McBride, who confessed that she had planned the killing for months, bought a handgun for that purpose, shot Wallace three times and waited to make sure Wallace was dead before turning herself in to police.

Investigators recovered three shell casings and the handgun at the scene. McBride was arrested and charged with murder; she later pleaded guilty and received a life sentence without the possibility of parole. Family members described Wallace as warm, funny and friendly and said her death devastated their close-knit family.

Anyone who knew Wallace or saw signs of trouble in her relationship with McBride is asked to share what they know.
