Police have identified two men from Illinois as the final suspects in the slaying of bartender Michael Dolan at Maggie O'Brien's on June 1.

Police provide this full account of the robbery-turned-homicide...

INCIDENT:  Homicide, Robbery
DATE/TIME:  6/1/09@11:42pm
LOCATION:  2000 Market Street (Maggie O'Brien's)
VICTIM:  Michael P. Dolan, 32 year old White male of the 1400 block of S. 18th Street in St. Louis
SUSPECT #1: Derrick Bell, 30 year old Black male of the 5000 block of Cote Brilliante (DECEASED)  (Bell is also known as Derrick Anthony)
SUSPECT #2: Devin L. Mosley, 26 year old Black male of the 1400 block of Central Avenue in Illinois, 62207
SUSPECT #3: Jacson D. Baker, 30 year old Black male of the 300 block of Agnes in Illinois, 62269 (name is spelled correctly, pronounced like "Jason")
 
Police received a call for a holdup where one person had been shot. Upon arrival, victim Michael P. Dolan was found to have been shot twice in the back. He was taken to the hospital where he died at 2:26 am.
 
The investigation revealed that around 11:30 pm, there were 5 people (including employees), inside Maggie O'Brien's when 2 Black males entered, showed guns and announced a holdup.

The 2 Black males ordered everyone to the ground.  The victim, a bartender at Maggie O'Brien's, ran to a back area of Maggie O'Brien's, with Suspect #1 following.  Suspect #2 continued to hold the bar patrons and employees at gunpoint, taking one person's wallet.  Several shots were heard coming from the back area of Maggie O'Brien's. 

When neither the victim or Suspect #1 returned from the back area, Suspect #2 -- who had been holding the bar patrons and employees at gunpoint -- fired one shot near the back area of Maggie O'Brien's, then ran.  Suspect #2 apparently also ran out. The victims who'd been held at gunpoint, discovered victim Michael P. Dolan and called police at 11:42 pm.
 
Around 11:47 pm, a Black male dropped another Black male off at Children's Hospital, telling hospital personnel that the man had been shot. He then left the hospital. Hospital personnel contacted police.  The injured man, who'd been shot once in the chest, died during surgery at 2:30 am. Though his identity was unknown at the time, (there was no identification located in his belongings), investigators suspected that the man could be one of the suspects in the Maggie O'Brien's attempted robbery and homicide. They began investigating this possibility due to the time that the man was dropped off at the hospital, the fact that the person who'd dropped him off left the hospital immediately, and that police had received no other calls for any "shootings" where the victim could not be located.
 
The Black male who was dropped off at the hospital was later identified by his mother as 30-year-old Derrick Bell. The investigation has since revealed Derrick Bell was Suspect #1. 
 
Derrick Bell was shot by Suspect #2, when Suspect #2 fired his weapon towards the back area of Maggie O'Brien's.
 
Investigators have since determined that Suspect #2 is Devin L. Mosley.  Investigators also determined that a third person, Suspect #3, drove the vehicle to Maggie O'Brien's, served as a look-out outside while Suspect #1 and Suspect #2 were inside.  Suspect #3 also drove from Maggie O'Brien's to the hospital and was the person who dropped Bell off at the hospital.  Investigators have since determined that Suspect #3 is Jacson D. Baker.

Suspect #3, Baker (left), was arrested in East St. Louis, Illinois on Monday, June 8th and is now in custody in St. Louis. The St. Louis City Circuit Attorney's Office has issued warrants against Baker for: 2 counts of 2nd Degree Murder (for victim Michael P. Dolan and suspect/victim Derrick Bell), 4 counts of Armed Criminal Action, 1 count of 1st Degree Robbery and 1 count of Attempted 1st Degree Robbery. A St. Louis City Circuit Court Judge set a bond of $1 million cash-only bond.
 
Suspect #2, Mosley, was arrested in East St. Louis, Illinois on Tuesday, June 9th. The St. Louis City Circuit Attorney's Office has issued warrants against Mosley for: 2 counts of 1st Degree Murder (for victim Michael P. Dolan and suspect/victim Derrick Bell), 4 counts of Armed Criminal Action, 1 count of 1st Degree Robbery and 1 count of Attempted 1st Degree Robbery.  A St. Louis City Circuit Court Judge has set a bond of $1 million cash-only for Mosley. He is in custody in St. Clair County, Illinois. The Circuit Attorney's Office handles extradition -- any questions about that process should be directed there. Since Mosley is not in custody in St. Louis, we do not have a mugshot to release of him at this time. You may wish to contact St. Clair County to get a mugshot.
 
Please note that neither suspect was arrested in Washington Park as some media outlets reported.
