MILWAUKEE -- Violent and unpredictable. That is how federal authorities describe Montrell Sanders.
Investigators believe he is one of 3 armed men who stormed a CVS a week before Christmas and may be responsible for a number pharmacy robberies at gunpoint.
On the street he goes by Monty. To federal authorities, Sanders is a wanted man considered armed and dangerous.
"This is a violent actor that needs to come off the streets," said assistant special agent Robert Botsch.
Botsch is head of the criminal branch. The FBI along with other local agencies have been investigating the spike in pharmacy armed robberies. Last year there were 52 drug stores hit by thieves.
A DEA report ranked Wisconsin as number two in a list of the top 20 states for armed pharmacy robberies last year.
The task force has centered around a crew terrorizing pharmacies for narcotics.
"Shy of someone getting shot, these are the most violent robberies that you can have," Botsch said.
Surveillance pictures captured the latest armed robbery of a CVS on Milwaukee's north side.
The brazen masked men stormed the store ordering customers and employees to obey their orders.
"When they didn't move fast enough that is when rounds were discharged," Botsch said.
In this "take over" style hold up one of the suspects jumped over the counter and ordered the pharmacist at gun point to open up a safe holding high-value narcotics. This same motive was repeated at a number of area pharmacies.
"We believe the one consistent part is Montrell Sanders," Botsch said.
Three men have been indicted on federal charges and are in custody, but Sanders has been able to allude police.
The FBI is offering a reward for his arrest.
