UPDATE: There have been confirmed sightings of quadruple murder suspect Austin Drummond, the Jackson Police Department said at 6 p.m. Monday.

On Sunday night, Drummond was recorded by a citizen’s camera system in the 700 block of Pipkin Road, according to police. Drummond is regarded as armed and dangerous.

The Jackson Police Department released two surveillance videos showing Drummond dressed in camouflage attire, sporting a backpack, and holding a rifle. In one of the videos, he is seen trying to open a door.

Earlier on Monday, Union University underwent a lockdown as officers were present nearby while the search for Drummond, the individual sought in a quadruple murder in West Tennessee, continued.

Numerous officers were observed blocking streets near Pleasant Plains Extension and Oil Well Road on Monday morning. This location is just a few miles from where Drummond’s vehicle was discovered on Friday.

The Jackson Police Department encouraged residents in the Pipkin Road and Pleasant Plains Road areas to examine all doorbell and security camera footage starting at 10 a.m. on Monday.

Police mentioned they were seeking video that might assist in the Austin Drummond case and requested anyone with pertinent footage to contact 731-425-8400.

Drummond has been on the run since last Tuesday, when the bodies of four family members were found in Lake County. His car was found in Jackson Friday and law enforcement thinks he could be in the area.

A third person has also been arrested and charged with Accessory After the Fact to First Degree Murder, according to the Tennessee Bureau of Investigation.

She has been identified by TBI as Dearrah Sanders.

The U.S. Marshals Service filed documents on Friday saying Drummond had possibly fled the state of Tennessee.

It has been a week since Drummond has been on the run.

USMS also announced that they will now pay up to $10,000 for information that leads to Drummond’s arrest. TBI and USMS had previously announced rewards of $7,500 each for information; the increased total reward is now $17,500.

Drummond is wanted on several charges, including first-degree murder and aggravated kidnapping in the deaths of four Dyer County family members whose bodies were found Tuesday, after an infant relative was found abandoned in front of a house.

Two men were arrested Saturday and charged as accessories after the fact.
