RALEIGH, North Carolina (WTVD) — Following the Raleigh Police Department’s press conference earlier this week regarding week-long rush hour shootings along and near I40, officers have been working hard to find and arrest the alleged suspect, Andrew Graney, 23.

Patrick Siewert has 15 years of law enforcement experience and is now a mobile forensics expert for Archer Hall. He salutes the work of the RPD.

“It looks a lot like the sniper shooting in Washington, D.C. I would say jumping on it, from a public safety standpoint, seemed pretty good to me. I mean, when you don’t have anything to do, it’s very difficult to conclude. Very good police work,” Siewert said.

ABC11 obtained the search warrants in which she described the two reports of a single gunshot fired at homes around Centennial Ridge Way and Shire Lane.

A gray Hyundai Sonata was seen on surveillance video in the area of ​​the calls around the same time. This information was used to collect and analyze data from cell towers where the shootings took place. The registered owner of the Hyundai was pinned in area five of the listings, giving officers a lead.

“Everyone’s cell phone is connected at all times, unless you put it on airplane mode or something, it’s always connected to a cell tower. The reason is that the cell network has to be able to find you and send you a call or text message It should be able to find you And so those passive connections are still there and that information is recorded by the cell phone provider,” Siewert said.

He said cellphone providers house the information for a certain period of time and a “dump tower” can be obtained via a search warrant or emergency request. Law enforcement can also use information from connected vehicles.

“I don’t like to rely on just one source of information. If I can get something to back that up, that would be great,” Siewert said.

Law enforcement used the same patterns and clues to keep Wake County safe and arrested Graney at his home Thursday afternoon.

Graney is being held without bail in the Wake County Jail.
