Nathan Michael Tonolini, 34, was shot multiple times and killed on July 15, 2015, in a Dallas townhome complex on the 9800 block of Brockbank Drive near Love Field. The shooter was his neighbor, 46-year-old Thomas Wilson, who was arrested just outside his home after reportedly waiting for police to arrive.

Tonolini was a DART employee and a Jehovah’s Witness who used sign language to help communicate with the deaf. He was married and had a step-daughter. Police searched Wilson’s townhome and found firearms and a suspicious package that prompted an evacuation until the bomb squad rendered the device harmless. The motive has not been provided by police.

Wilson was later sentenced to 70 years in prison for Tonolini’s murder. Tonolini’s family and neighbors remembered him as a good man and a positive presence in the neighborhood.

If anyone knew Nathan, his routine, or saw anything unusual in that townhome complex around July 15, 2015, please share what you know.
