YOUNGSTOWN, Ohio - DeWaylyn Colvin of Youngstown is already serving 11 years in prison related to his drug ring.
Youngstown police investigators say he called the shots and ordered his alleged accomplices to carryout four murders in the city over the past two years.
"It is believed that these murders were committed to solidify his control over his heroin distribution network," sayd Youngstown police Lt. Doug Bobovnyik.
In April of this year, Colvin, along with Michael Austin Junior and Hakeem Henderson were indicted by a Mahoning County Grand Jury for the November 13, 2011 killing of 23-year-old Adam Christian.
Christian was found shot to death on Woodcrest in Youngstown.
Just days later, the man who police believe was ordered to kill Christian, Raymond Ramel Hayes was also found murdered on the East side.
Police suspect it was an attempt by the group indicted to silence him about the crime.
"And you can see that happened on november the 16th, three days after the Christian murder," says Bobovnyik.
Now, Colvin and Austin have been charged with aggravated murder in two other killings and an attempted homicide.
On September 19, 2012 two victims were found shot to death inside a car on Benford Lane in Youngstown.
The victims were Keara McCullough and Ryan Kieth Slade.
Detectives contend, while Slade was part of the drug trade and ordered killed after disrespecting a Colvin associate.
The female victim, McCullough was tragically in the wrong place at the wrong time.
"Our investigation revealed that she was a completely innocent victim," he says.
Colvin is in a state prison and Austin is also in custody.
However, police say Hakem Henderson is still on the run and should be considered armed and extremely dangerous.
