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

Drummond was seen on a citizen’s camera system in the 700 block of Pipkin Road on Sunday night, police said. Drummond is considered armed and dangerous.

The Jackson Police Department released two surveillance videos showing Drummond wearing camouflage clothing and a backpack, and carrying a rifle. In one video, he attempts to open a door.

Earlier Monday, Union University was placed on lockdown, and officers were seen nearby as the search continued for Drummond, the man wanted in a quadruple murder in West Tennessee.

Several officers were seen blocking streets near Pleasant Plains Extension and Oil Well Road on Monday morning. The location is just a couple of miles from where Drummond’s vehicle was found Friday.

State troopers were seen checking vehicles entering Cherry Grove Apartments, near the university.

The complex is where 23-year-old Dearrah Sanders was arrested Monday. She is the third suspect charged with being an accessory after the fact.

The Jackson Police Department urged residents in the Pipkin Road and Pleasant Plains Road areas to review all doorbell and security camera footage beginning at 10 a.m. Monday.

Police said they were seeking video that may assist in the Austin Drummond case and asked anyone with relevant footage to call 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 on Friday, and law enforcement thinks he could be in the area.

The U.S. Marshals Service filed documents on Friday, stating that Drummond may have fled the state of Tennessee.

It has been a week since Drummond went 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.
