A career criminal accused of murdering a family of four and abandoning their baby once warned jurors would 'regret' convicting him in a past court case.

Austin Robert Drummond, 28, remains on the run after he was identified as the primary suspect in the chilling Tennessee quadruple homicide of Adrianna Williams, 20; Matthew Wilson, 21; Cortney Rose, 38; and Braydon Williams, 15, last month.

Drummond was released from prison in September after serving 13 years for an armed robbery he committed at a Circle K gas station.

And it has now emerged that District Attorney General Jody Pickens vehemently opposed his conditional early release in a previous hearing in June 2020, writing a letter to the Tennessee Board of Parole warning he was 'not capable of living among society.'

'This office strongly opposes his early release on parole,' she wrote, describing him as a 'dangerous felony offender' and member of the street and prison gang, Vice Lords.
