COLUMBUS  (WCMH) — Robert Lee Adams was sentenced to life without parole for his part in the quadruple murders at a South Linden home in June of 2015.

Adams was sentenced on each of the four counts of murder, and 11 years on the attempted murder. He also received an additional two years for the gun specification. His sentences are to run consecutively, according to the judge.

During the sentencing hearing, Adams addressed the court and apologized.

Adams pleaded guilty Tuesday to four execution style murders and a fifth attempted murder.

According to Franklin County Prosecutor Ron O’Brien Adams, 29, pleaded guilty to the murders of Michael Ballour, 41, Daniel Craig Sharp, 26, Angela D. Harrison, 35, and Tyajah N. Nelson, 18, that occurred in the basement of Ballour’s house located in the 1600 block of E. Hudson Street in South Linden, June 13, 2015.

Adams was accompanied by juvenile Jordyn D. Wade, age 16 at the time of the murders. Wade was sentenced to 172.5 years to life on September 13, 2016.

The pair robbed the victims, ordered them to the basement, and Adams then shot the victims, murdering four of them, while Wade stood at the top of the stairs with his gun drawn. After the shooting Adams and Wade fled the scene.

One of the five victims survived the shooting and stumbled from the residence where they sought help. Wade was picked up shortly thereafter.
