Just five minutes after that call, St. Paul police responded to an emergency at the corner of Minnehaha Avenue and Cypress Street where there was a report of two men passed out in a running car.

The officers had to break open a car window to help firefighters reach the two men in the car.

Then, about an hour-and-a-half later, rescue crews were called to the 1700 block of Blair Avenue where it was reported another person had overdosed.

St. Paul police issue overdose alert after 6 overdoses in 3 incidents

New BCA stats show Minnesota had over 350 drug overdoses in June, 22 deaths

Mike Smith, President of the St. Paul Firefighters Union, told 5 EYEWITNESS NEWS situations like the one Saturday morning tax the East Side ambulance crews to their limits.

"When you have five calls going out almost simultaneously, and we had five within 10 minutes of one another, it creates a burden because it depletes the East Side crews entirely," said Smith.

Smith said the quick action of fire crews and police officers saved six lives and is a good reminder for the public to know how stretched and stressed crews are right now.

"With everything happening this summer we all have been stretched pretty far," said Smith. "It is not uncommon for our crews to be depleted in one district and have to rely on other districts to come in and assist."

St. Paul Police told KSTP their investigation is still underway, but it appears the six people who overdosed thought they were buying cocaine and there is evidence to suggest it could have been laced with a near-fatal dose of Fentanyl.

All of the drugs involved in these six overdoses seem to have come from the same supplier and St. Paul Police said it looks like all six who survived the ordeal will recover.

No arrests have been made and investigation is ongoing.
