Three vehicles parked in driveways across Mount Prospect were broken into overnight, with security footage showing two masked suspects stepping out of a white SUV to search the cars before fleeing — and one of them appeared to be holding a handgun.

Three Driveways, One 34-Minute Window

According to Daily Herald, Mount Prospect police are investigating the break-ins, which struck the 300 block of South Louis Street, the 800 block of South Elm Street, and the 900 block of Greenfield Lane. The incidents occurred early Monday morning, between 3:59 a.m. and 4:33 a.m., a tight window that suggests the suspects moved quickly from one target to the next.

Victims told investigators their vehicles had been left unlocked in their driveways, and afterward they noticed that items inside had been moved around, the same report notes. Security footage reviewed by police showed two masked suspects getting out of a white SUV, opening car doors, and then leaving — a pattern that played out at each of the three locations.

What the Suspects Were Wearing

Police said the suspects were dressed in dark masks, light-colored zip-up hooded sweatshirts, dark pants, and gym shoes, per the report. One of the two appeared to be holding a handgun during the encounters.

Mount Prospect police are asking anyone with information to call the Investigations Section at (847) 870-5654. No suspect names, arrests, or charges have been announced in connection with the overnight break-ins.

A Month of Similar Reports in the Village

The new break-ins follow a separate round of attempted car burglaries on the east side of Mount Prospect described in an earlier dailyherald.com report. In that case, home security video captured three people getting out of a vehicle near a Ram 1500 pickup on the 1700 block of Mura Lane at about 1:17 a.m., with one approaching the truck while holding what appeared to be a handgun. The homeowner told police nothing appeared to be missing from the pickup afterward.

That same report described two more attempted burglaries on the 1900 block of Seneca Lane around 1:08 a.m., where masked individuals tried door handles but couldn't get inside because the vehicles were locked. Video from those incidents also showed suspects holding what appeared to be handguns. It remains unverified whether Monday's break-ins are connected to that earlier string of attempts.
