He is allegedly part of a violent criminal organization based in Middletown believed to be involved in multiple homicides. Federal and local law enforcement agencies executed a series of search warrants this summer in Middletown, Miamisburg and Dayton.

In 2011, Conley, then 18, was sentenced to five years in prison for killing a man he intentionally ran down with a car. He pleaded guilty to involuntary manslaughter in the death of 20-year-old TaShawn Smiley as part of a plea deal before a Butler County grand jury could consider a murder charge against him.

He is approximately 5 feet 11 inches tall and 175 pounds. He has black hair and brown eyes.

Anyone with information regarding Conley is asked to call 1-800-CALLFBI.
