Jurors on Friday afternoon convicted Derrius Shamar McKinney, a/k/a Bam, of the Sept. 13, 2012 armed robbery and aggravated assault. The victim, a 59-year-old man, had just used the ATM at the Bank of America branch at 2475 S. Cobb Drive when the attack occurred shortly before 9 p.m.
But jurors acquitted McKinney, 23, of Marietta of another armed robbery and aggravated assault that occurred at the same ATM a week earlier.
None of the victims in either robbery were able to identify the suspects because it was dark at the time and lighting was poor.
In the Sept. 13 robbery, DNA found on cigarettes near where the victim said the perpetrator’s car was parked matched that of McKinney. The victim was hit in the head with a gun and robbed of $160.
Assistant District Attorney Maurice Brown said McKinney, along with a co-defendant, were trying to get something for nothing.
“That goes against the American way,” said Brown, who prosecuted the case for District Attorney Vic Reynolds' office. “You can’t expect to deprive hard-working Americans of the fruits of their labor and not suffer the consequences.”
This morning, Cobb Superior Court Judge Mary E. Staley sentenced McKinney to the state’s recommendation of 40 years.
He was represented by attorney Bryan Lumpkin of Marietta.
Co-defendant Shawn Thomas already pleaded guilty in the case and was sentenced to 15 years, with 10 years to serve in custody.
