Aug. 3 (UPI) -- Two people were arrested over the weekend with helping a suspect accused of quadruple murder, according to authorities who on Sunday said they have increased the reward for information leading to the arrest and location of Austin Robert Drummond.

Drummond, 28, is accused of killing a family of four in northwestern Tennessee last week, and has been on the run since.

The U.S. Marshals Service on Sunday announced a reward of $10,000 for information that leads to his arrest for a total of $17,500 when combined with the money being offered by the Tennessee Bureau of Investigation.

"It's past time -- let's get Drummond into custody," the Dyer County Sheriff's Office said in a statement in response to the announcement. "See something, say something. We can't get distracted -- stay focused on the singular mission of finding Austin Drummond. Keep his name and face all over social media."

Drummond has been charged with four counts of first-degree murder, four counts of a felon in possession of a firearm and one count each of aggravated kidnapping and possession of a firearm during the commission of a dangerous felony in connection with the deaths of James M. Wilson, 21, Adrianna Williams, 20, Cortney Rose, 38, and Braydon Williams, 15.
