The paralegal who allegedly used her position to expose snitches on behalf of her gangster son appeared in court yesterday in New York.

Prosecutors said Tawanna Hilliard, 44, used government computers while working at the US New Jersey Attorney's Office to identify Bloods gang members she thought ratted on her son.

Hilliard's son, Tyquan, is serving a 10-year prison stretch for robbery in New York and is a member of the 5-9 Brims set of the Bloods gang.

She phoned her son in April 2016 and told him she had 'looked up' cases on behalf of the 5-9 Brims who wanted to find out who had broken their code of silence, the Washington Post reported.

In May 2018, Tyquan Hilliard and another man, identified only as John Doe, robbed an AT&T store in Monticello, New York, flashing an automatic handgun.

They fled with brand new iPhones and iPads worth $3,000, the Post reported, and led police on a 125mph chase in a white jaguar before crashing.

After their arrest, Hilliard allegedly complained in text messages her son would have no line of defense because the co-accused was trying to 'jam up' her son.

What she meant was that he was going to give information to the police.

Authorities said Hilliard uploaded a video to YouTube where her son's co-defendant was talking to police.

The YouTube video, which was posted to 'out' the co-defendant was entitled 'NYC Brim Gang Member Snitching Pt. 1' and was obtained as discovery material in Tyquan's case.

On searching her home in Flatbush, Brooklyn, police found text messages she sent saying that Tyquan 'has no line of defense because his co-d told everything.'

Another message said: 'John Doe' was 'giving up murders, victims, shooters and all... SMH.'

She plead not guilty to the charges of tampering with witnesses, obstruction of justice and harassment of witnesses (pictured, the US Attorney's Office in New Jersey)

The video caused the co-defendant, identified as 'John Doe' in the court records, to receive death threats while in prison. His family were also said to receive similar threats.

Hilliard was released on $75,000 bond but warned not to contact her son and to avoid social media.

She plead not guilty to the charges of tampering with witnesses, obstruction of justice and harassment of witnesses.
