HOUSTON – An unsettling string of Snapchat videos has one west side community on edge.

The clips appear to show two people shooting about 14 rounds out of a moving car early Tuesday morning.

"It's a little bit scary. You don't know where the shots are going," worried resident Bill Kraft said.

Based off the location of the Snapchat map, it was geo-tagged, or tracked, right along Highway 6 behind Kraft's home. He said he heard a loud sound he thought was a car backfiring.

"Then I heard two more rapid shots, which I thought, 'This isn't a car. It's got to be something else,'" Kraft said.

WATCH: Snapchat videos show people firing guns out of vehicle in west Houston

On Wednesday, a day after the video was posted, KPRC 2 drove the same path the video appears to have taken, and it wasn't long before we discovered more possible evidence connected to the videos.

KPRC 2's crew found what appears to be a bullet hole in a business sign and some shell casings.

KPRC gave the shell casings to a detective on Thursday, the same day the department announced it was investigating the incident.

Police will work to determine if the shell casings are, in fact, connected to what was seen on video. Police are also still trying to determine if the hole seen in a sign is connected.

Another worried resident, who didn't want to be identified, said, "It's absolutely terrifying to know that somebody is just free shooting down the street."

The Houston police said Wednesday that they were not investigating the case, since a formal complaint hasn't been filed yet.

However on Thursday morning, HPD tweeted, "HPD actively investigating 2 people firing guns from moving car in a West Houston Houston neighborhood (and) posting video to Snapchat"

Houston police also tweeted that they have interviewed possible witnesses and the homeowners association.

KPRC 2 also spoke to a social media and tech specialist to get their take on the video.

"First impression is real video; it is very difficult to fake things through Snapchat. Your location on the app is tied to your location in real life. There's not a way to fake that," said Kristy Gillentine, vice president of public engagement for Drive West Communications and a social media specialist.

For now, worried residents are left calling on police to look into to the matter sooner, rather than later.

"I think if you have video proof of it, Snapchat or otherwise, it's important to follow up on it," said the worried resident.

Houston police asked for the public's help for information by calling Crime Stoppers at 713-222-TIPS and the HPD non-emergency line at 713-884-3131.
