Landlord Mr Jones, 46, died at The Blossoms public house in Holyhead on Friday afternoon.
Following a stand-off with police on the roof of a neighbouring pub, a 24-year-old man was arrested on suspicion of murder. He remains in custody
A family tribute read: "A partner, soul mate, father, brother, uncle and our best friend. We love you."
A post mortem examination was carried out on Saturday but North Wales Police say they are not releasing Mr Jones's cause of death yet.
Officers have made a specific appeal to speak to people who were on board the number four Arriva Bus which left Bangor bus station at 14:00 GMT on Friday and arrived at Summerhill in Holyhead at about 16:00.
Det Chf Insp Iestyn Davies said: "It is understood that the bus was caught in traffic around the Black Bridge area of Holyhead as events at the Blossoms public house were unfolding."

Mr Beheshti died after being held on charges of "actions against national security on social networks".
Following his arrest on 30 October, he was handed to police for interrogation and died on 3 November.
The exact circumstances of his death remain unclear. Some reports have suggested he was tortured.
The Tehran prosecutor's office says the main cause of Mr Beheshti's death could be physical shock - caused by the brute force applied to sensitive parts of his torso - or psychological pressure.
"It is not possible to determine the exact cause of death," it said in a statement quoted by Irna news agency. "But the most likely cause leading to death may be shock."
The statement notes that a thorough forensic investigation has been carried out and that prosecutors have obtained witness statements from Mr Beheshti's inmates and prison wardens.
Neither the statements nor the forensic results are in the public domain.
An earlier coroner's report said his body had "signs of wounds" but no broken bones, according to the semi-official news agency Mehr.
Mr Beheshti's death sparked an international outcry. Last week, three people were reported to have been arrested and subsequently, according to an opposition website, released.
According to opposition website, Kalameh, the suspects had been involved in Mr Beheshti's interrogation.
Mr Beheshti's mother has been forbidden to speak to the press. But an opposition website quoted her as saying she had been offered "blood money" in compensation.
She added: "I said I didn't want any. What I want is for the world to know that they killed my son. They killed Sattar."
It is thought Mr Beheshti was targeted for his writings on political and social issues on his blog and on Facebook.
The blogger spent one night in Tehran's notorious Evin prison on 30 October, where he wrote an official complaint to prison authorities alleging ill-treatment, before being moved to an unknown location.
His death provoked criticism from politicians and human rights groups, Amnesty International said Mr Beheshti had complained of being threatened the day before his arrest.

The park authority's planning committee said the land involved was earmarked for housing.
However, it added that the developer's three planning applications for the project were "not deemed to meet with a range of other planning policies".
Aviemore and Highland Developments Ltd, part of the Tulloch Homes Group, had sought approval for the scheme.
The housing project has been going through the planning process for more than 10 years.
Among the planning committee's reasons for refusal were that environmental impacts had not been fully assessed.
Rare red squirrels, capercaillie and wood ants had been recorded in the area.
Committee members were also told the village's Carr Road was unsuitable as an access for the majority of houses proposed.
Carrbridge, known for its 18th century packhorse bridge, has a population of about 700 people.
