Investigators used Stallworth’s phone to track hundreds of phone calls and incriminating text messages exchanged with Lane in the run-up to the shooting, police said during testimony.
Lane’s attorney, Max Richardson Jr., said Stallworth was a drug addict out to rob Perez.
“He’s a liar,” Richardson told the jury of Stallworth during closing arguments Monday.
Stallworth, 31, pleaded guilty to murder, felony murder, aggravated assault and gun charges, Channel 2 reported, and awaits sentencing.
Sentencing for Lane will be set at a later date.
Both men are being held at the DeKalb County jail.
