Mr Justice Rooney has asked the public for assistance in determining why the 14-year-old left his home on Fitzroy Avenue in Belfast at 5.40pm on June 21, 2020 before cycling through the city centre.
Anyone who knows why Noah left home, where he went, whether he met anyone and what happened his flip-flops and/or his headphones has been urged to contact the Coroners Service for Northern Ireland.
The coroner is also hoping to hear from anyone with knowledge of Noah being out in the early hours of the morning on any other occasion.

The teenager was captured on CCTV cycling from Northwood Drive at around 6.08pm which is the last known time Noah was seen alive.
He had left his flat on the corner of Fitzroy Avenue and Dudley Street earlier on the same day of his disappearance at around 3:34am before returning at 4.08am during damp and drizzling weather.
Footage captures Noah’s departure and return to the property.
“When Noah left home at approximately 3:34am, he was casually dressed in dark coloured knee length shorts and a light or white coloured T-shirt.
“He was wearing flip-flops and carrying over-ear headphones in his right hand.
“On leaving the address Noah appears to turn right, walking west in the direction of Queen’s University.

“When Noah is next captured on CCTV, on his return home, he was on University
Street, coming from the direction of Ormeau Road and walking in the direction of
Queen’s University.
“From there, he turned left onto Dudley Street and then right onto Fitzroy Avenue, turning immediately into his home address.
“Noah re-entered through the front door of 65 Fitzroy Avenue at approximately
4.08am.
“It is apparent from CCTV footage that he was barefoot on his return, and neither his flip-flops nor his headphones are visible on his person.”

Following a missing person search which lasted six day, Noah was subsequently found dead in a storm drain.
The inquest before a jury, which has been delayed several times previously, had been scheduled to begin next month.
Earlier this month, a hearing at the Royal Courts of Justice was told there were “significant concerns” that the evidence would not finish by Christmas.
The hearing was postponed again until early in 2026.
