Steven Schelmety, 32, was killed on February 15, 2019, while opening the bay door at his business, Artillery Motor Sports, near Lakeland Linder International Airport. He and his father, Estaban, were ambushed; Steven was struck by multiple bullets and died at the scene while his father was critically injured and taken to Lakeland Regional Health.

Investigators identified family friend Juan Alejandro Vargas Diaz, 28, as the shooter and arrested him in Miami on February 23, 2019. Surveillance footage and toll records reportedly placed his vehicle on the drive from Miami to Lakeland and back that night. Authorities say Vargas Diaz fired at least 21 bullets from a modified high-capacity 9mm EVO 3 S1 and waited outside the business for several minutes before opening fire. He was charged with first-degree murder; the motive has not been reported.

Did anyone who knew Steven, his work at Artillery Motor Sports, or his connections in Lakeland notice anything unusual in the days before February 15, 2019?
