Omaha Police say up to three men could be responsible for 19 robberies across the metro.

It's a massive investigation that includes Sarpy County, LaVista, Bellevue and Council Bluffs Police Departments.

Investigators believe over the past three months, the robbers targeted ten gas stations throughout Omaha and another nine in Council Bluffs and Sarpy County, all during the overnight hours.

Jiwan Guragain is a manager at Omaha Liquor and More, one of the businesses hit. He says back on July 27th his store was robbed at gun point. The men walked away with more than $2500 in cash and cigarettes.

"Knowing that other places are being robbed and some a couple of times. It kind of scared us," he said.

Since then they've taken a few extra precautions to prevent robberies. They've added a doorbell to the outside (for customers after dark) and surveillance cameras inside and around back.

But Omaha Liquor and More isn't the only place that's been hit.

Michelle Smith first told Channel Six News about one of the robberies in July. Smith said a man pointed a gun at her and demanded cash. It happened about 6:30 in the morning at the LaVista Sinclair gas station near 84th and Park View Blvd.

“It's something I think about every single day; it was very scary,” Smith said. “Tons of trouble sleeping, I took the weekend off, still can close my eyes and picture it every single day.”

A store in Council Bluffs was also robbed. At the time, police believed at least 7 other robberies were connected.

As of Tuesday, that number rose to 19.

Omaha Police released a series of surveillance photos. They believe the same men are responsible. The photos included one from a robbery at a Council Bluffs Kum & Go on the 4th of July. In another photo the gunman is seen wearing gloves, standing at the counter. That robbery, like others police said, had the same M.O.

"Two black males armed with handguns came in and demanded cash from the clerk in here; they took off eastbound on foot,” Omaha Police SGT. Jeff Chubb said.

Police said the men hit the same gas stations in Council Bluffs more than once. One photo showed the robbers face, determined to rob again.

Authorities also released a surveillance photo from the LaVista Sinclair gas station. It was a reminder of why M'lissa Brown, a store manager and her employee, Michelle wanted to see the men picked up and taken off the streets.

“I hope they get caught and they get sentenced severely because they're scaring a lot of people,” Brown said. “It's not just here it's all over.”

The two suspects police are looking for are both roughly six foot, thin to average build, mid 20's to 30's and wearing dark clothing over their face.

Anyone with any information on the robberies are asked to call Omaha Police at 402-444-7867.
