Investigators are reporting that the 21-year-old suspect responsible for the mass shooting in Highland Park, Chicago allegedly planned the mass casualty event for weeks.
Lake County Sheriff’s Department Deputy Chief Christopher Covelli spoke about the latest findings on gun man Robert E. Crimo III during a press conference on Tuesday.
Covelli told reporters that Crimo acted alone and reportedly dressed in women’s clothing in an attempt to cover his tattoos and blend in with the crowd as he made his escape.
It was also reported that Crimo fired around 70 shots from an AR-15-style gun while on the roof of a commercial building overlooking a 4th of July parade.
The shooting left seven people dead and at least 30 injured.
According to several reports, the shooting occurred in an area considered to be the prime viewing point of the parade.
Crimo, whose father once ran for mayor of Highland Park, was eventually taken into custody without incident during a traffic stop hours after authorities released his photo to the public.
Investigators have interrogated the suspect and reviewed his social media but have come up with no possible motive at this time.
Highland Park Mayor Nancy Rotering also noted that though there is an assault weapons ban active in the city, Crimo obtained the weapon legally.
Authorities have not filed criminal charges.
