The family of a man fatally shot by a New Orleans Police Department officer last month protested along with supporters outside NOPD headquarters on Thursday night.

The mother and sister of Arties Manning III said they are still seeking answers in the investigation into his Jan. 24 shooting at the hands of Ofc. Terrance Hilliard, who was working in plainclothes on an armed robbery investigation when the shooting happened.

Manning's family members were joined by more than 30 protesters for the candlelight memorial.

Aside from a brief initial statement by Police Superintendent Michael Harrison, authorities have not said whether they believe Manning, who had no apparent criminal record, was involved in the armed robberies that Hilliard was trying to solve.

Manning's mother, Natasha, said she wanted to ask Hilliard to "look deep inside his heart and ask himself, did I just kill another black man for nothing?"

"This starts with you, Terrance Hilliard. Where is your apology?" Natasha Manning said.

Police said that Arties Manning pointed a gun at Hilliard in a courtyard at the Carriage House apartment complex in New Orleans East before the officer opened fire, striking him three times and killing him.

Independent Police Monitor Susan Hutson said last week said that she still has many questions about the ongoing Public Integrity Bureau investigation into the shooting.

Meanwhile, one of the federal monitors who also has oversight authority for the Police Department offered a guarded statement on the case after a court hearing on Thursday.

"The process is working the way it should work. They are doing a thorough investigation. That’s all I can say about a pending matter," said Jonathan Aronie, the court-appointed lead monitor for the NOPD's reform process.
