RALEIGH, NC (WTVD) — Following the Raleigh Police Department’s press conference earlier this week regarding a week of rush hour shootings along and near I40, officers worked hard to find and arrest the alleged suspect, 23-year-old Andrew Graney.

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

“Sounds a lot like the DC sniper shootout. I would say that jumping on it from a public safety perspective, I thought was pretty good. I mean, when you have nothing to go on, it’s very hard to end. Your arms around her. Pretty good police work,” Siewert said.

ABC11 obtained the search warrants outlining the two reports of a single shot being fired at homes around Centennial Ridge Way and Shire Lane.

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

“Everybody’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. So the reason for this is that the cellular network needs to be able to find you, send you a Call or send messages. They have to be able to find you and that way, those passive connections are always there and that information is recorded by the cell phone provider,” said Siewert.

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

“I don’t like going to one source of information. If I can get something to confirm that, that would be great,” Siewert said.

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

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