WARREN (WWJ) - A man police say is a suspect in a string of armed robberies across three counties is behind bars.

Wilbert Vincent Boswell, 65, was arrested by members of the Warren Police Department Special Operations Unit at a hospital in Detroit on Monday.

According to Warren police, on Feb. 26, Boswell approached a cash register at the Burlington store at Dequindre and 12 Mile Rd. and told an employee: “Don’t make any noise, I have a gun and I’ll shoot you.”

It's alleged he then demanded that the employee to open the register and give him all of the money inside. Once he collected the cash, around $500, police said Boswell repeated to the employee that if she made any noise he would shoot her, before fleeing the store.

While investigating the crime, police learned that the same suspect was wanted in a string of store robberies just days apart, including:

The armed robbery of a Family Dollar in Eastpointe on Feb. 17, 2020

The armed robbery of a Shoe Carnival in Troy on Feb. 20, 2020

The armed robbery of a Family Dollar in Detroit on Feb. 20, 2020

Boswell was initially arrested for a parole violation, but on Wednesday he was charged with armed robbery in the Burlington incident.

Boswell, who remains in custody awaiting arraignment, has including several prior criminal convictions for assault with intent to rob while armed, armed robbery, felony firearms, felony habitual offender and parole violation, according to Warren Police Commissioner Bill Dwyer.

With such an extensive criminal history, Dwyer isn't happy that Boswell was out roaming free.

"The bottom line is he should've received more time; he's habitual." Dwyer told WWJ's Sandra McNeill. "I'm disappointed with the system when it comes to releasing these career, habitual, dangerous criminals who are really not serving, in most cases, even half of the sentence that's given to them."

Additional charges for his other alleged crimes are expected as the investigation continues.
