St. Petersburg, Florida-- Many new developments have been released in the case of a Family Dollar armed robbery, turned police chase, turned fatal car crash late Thursday night.

A St. Pete Police report sent Friday says they have identified the two suspects involved in the fatal crash, and adds that they are now working to identify a third suspect- when their initial report only mentioned the two involved in the fatal crash.

The female suspect in the police chase, and front seat passenger during the crash, has been identified as 19-year-old Dijon Senay Jackson of Pittsburgh, PA. She did not survive.

The male armed robbery suspect, and driver during the chase, has been identified as 31-year-old Alfonso Eugene Mackey. He is now at Bayfront Medical Center with serious, but non-life threatening injuries.

Police are unsure of Jackson's involvement in the entire scheme- the report saying they don't know when Jackson got into Mackey's car, or what her role was in the armed robbery that started the police chase...

The robbery:

According to investigators, it was just before 8 p.m. when Mackey and an unidentified black, male suspect robbed the Family Dollar Store, off 16th Street N in St. Pete. 

Mackey, who was armed with a long-barreled pistol, entered the store first and immediately demanded the cashier to open the cash register, says the update.

The second, unknown suspect, went in shortly after with his face covered as Mackey continued to demand money from the cashier, who was reportedly too nervous to open the register. 

Mackey then fired his gun, and reached under the counter to steal several packs of cigarettes.

Those at the scene reportedly told officials the unknown suspect appeared to be on the phone before they both fled from the store. 

The chase:

A witness outside told officials the two suspects left in a silver, Chevrolet Monte Carlo that was parked behind the store.  

Police reportedly spotted the car within 10 minutes, but when a marked cruiser attempted to stop the suspects, they sped away.

Officers followed what looked like three passengers in the getaway car, but after briefly losing them, they say only Jackson and Mackey were inside.

They believe the unknown armed robbery suspect got out during that time.

After sighting them again, the chase continued, but not for long. 

The crash:

Two officers tried to get Mackey to pull over, but his reckless driving reportedly caused his breaks to lock, and his car drove directly into a tree near the intersection of 15th Ave. S and 40th St. S. 

Jackson was pronounced dead at the scene, and Mackey was rushed to the hospital as a "trauma alert". 

Officers on the scene found the firearm Mackey used, and the stolen cigarettes from the armed robbery, inside the car.


Investigators are still working to identify the second male suspect in the armed robbery. The report describes him as follows:

  • Black male
  • 20's - 30's
  • Dark complexion
  • Wearing a black jacket with red around the collar and down the front of the jacket, faded-wash blue jeans, and a black New York Yankees baseball cap- and a black covering over his face

As for Mackey, officials say he faces Armed Robbery charges, Fleeing and Eluding charges, and others for Jackson's fatality during the crash. 

Police say they believe Jackson had been in town for several weeks on vacation. She was arrested in Pinellas County last week for not having a driver's license.
