The San Benito Police Department, Harlingen Police Department and Weslaco Police Department have joined forces to track down the suspect they believe targeted four businesses throughout their cities Wednesday.
The suspect robbed four different locations at either knife and gun point - a GameStop in San Benito and one in Harlingen, an EZ Pawn on the 1700 block on Tyler street in Harlingen and an EZ Money Loans in Weslaco.
Surveillance video shows the suspect at the Weslaco location walk into the business and go directly towards the cashier with his weapon drawn.
Weslaco Police Chief Michael Kelley said this could prove a serious situation.
"We're afraid if it continues somebody is going to get hurt or killed and we TMd like to catch this guy before it got to that point, Kelley said.
San Benito police said it's hard to determine if this is an experienced crook. No employees were harmed in any of the holdups, but authorities adds he's considered a serious threat.
"We don't believe he used any profanity but he did make his point clear by displaying his weapon at the staff, San Benito Inv. Rogelio Banda said. Just the mere fact that he's using a weapon makes him a very dangerous suspect at this time."
Witness descriptions varied slightly from location to location, but Harlingen police said the surveillance video is consistent.
The suspect made off with about $100 from both Harlingen locations.
"The amount taken is really not relevant, the fact that he used a weapon (when he committed) the theft is what makes it more serious," Harlingen Sgt. John Parrish said.
Authorities said at this point it doesn't matter what agency makes the arrest, they just want the suspect behind bars.
"We will be looking at all possibilities and getting with all agencies involved to help solve this, Parrish added.
