William John Wolff was a 41-year-old professor at El Paso Community College who was found shot to death on December 5, 2015, outside his brother’s law office in Northeast El Paso. The killing occurred amid a contentious child custody dispute with his ex-wife, Erika Wolff. Wolff had been awarded custody of his 2-year-old daughter; investigators say Erika Wolff and her parents fled to Mexico with the child, prompting charges of interfering with child custody.

Authorities charged Erika Wolff, her mother, and her father, Javier Arrellano Quinones, in connection with the custody interference. Quinones was also charged in William Wolff’s murder; prosecutors say he approached several people about hiring a hitman to kill Wolff. The case drew attention for how a custody battle escalated into lethal violence and legal action. Wolff is remembered by colleagues and family as a dedicated educator and family man.

Did anyone in El Paso have information about Wolff’s movements or the custody dispute in late 2015?
