Michael Terrence Gipson, 48, and Walter L. Keller, 45, have been arrested and charged with aggravated robbery.

Last week the police, seeking additional information in the case, released a video of two suspects in the case at a gas station directly following a robbery.

Gipson and Keller are accused of following people home and robbing them at gunpoint when they pull into their driveway.

Police are investigating three similar robberies that occurred in a two-day period in May.

On May 18, 2016, at about 9:47 p.m., two victims pulled into their driveway in the 6100 block of Oakcrest before being robbed at gunpoint.

On May 19 a  female victim was robbed around 10:15 p.m. after she pulled into her driveway in the 6800 block of Blackwood. A few minutes later, around 10:20 p.m., two more people were victimized after pulling into their driveway in the 6200 block of Saratoga.
