Mr Neill, who was 45, was stabbed to death during a fight in the Parkmore area of the Co Armagh town in the early hours of 16 September.
Daniel McCartney, aged 20 and from Enniskeen, Drumgor in Craigavon, has appeared in court charged with murder - which he denies.
Police returned to the scene of the incident in the early hours of Sunday morning in a bid to gather more information about what happened.
They spoke to local people and mounted vehicle checkpoints.
Detective Chief Inspector Gareth Talbot said: "We are working to piece together the events of the morning of Sunday, 16 September.
"We need to hear from anyone who noticed any kind of activity around David's house on that morning, whether this was people gathered in the area, people calling to houses in the area or vehicles around the area.
"We also want to talk to anyone who spoke to David on Saturday night prior to his death or early on Sunday morning."
Mr Neill was treated for his injuries at the scene of the attack but later died in hospital.
A detective told Lisburn Magistrates Court last month he believed he could connect Mr McCartney to the incident.
A barrister representing the accused - who was remanded in custody - said he denies having a knife in his possession on the night of the attack.
Ch Insp Talbot said the PSNI are doing everything in their power to solve the case.
He continued: "The community in Craigavon have been shocked by the death of David.
"David was in his own home whenever it was attacked. He was subsequently murdered. The impact of this tragedy is not something we underestimate and I would like to reassure the community that we are doing everything in our power to find out exactly what happened at Parkmore on the night in question."
Anyone with more information has been asked to come forward.
