Enis Mrvoljak, 48, was one of three men killed when a coworker opened fire at Advanced Granite Solutions in Edgewood, Maryland, on October 18, 2017. The shooter, identified as 37-year-old Radee Labeeb Prince, gathered several coworkers before beginning the attack; two other employees were critically wounded that morning. After the workplace shooting, Prince fled and carried out a separate shooting at a used-car dealership in Wilmington, Delaware, where that victim survived. Prince was captured later the same day in Newark, Delaware.

Prosecutors charged Prince with multiple counts tied to the rampage; his defense asserted bullying at work and later pursued an insanity defense, while a jury ultimately found him guilty of three counts of first-degree murder and two counts of attempted first-degree murder. The judge ruled he was criminally responsible and imposed consecutive life sentences for the Maryland murders and attempted murders, to be served after a 40-year sentence for the Delaware shooting.

Did anyone who worked at Advanced Granite Solutions or who knew Enis remember tensions at the shop before October 18, 2017?
