Robert and Ann Grogan are parents of Daniel and Francesca Grogan. Liam Hickey is a cousin of Daniel and Francesca.
The court heard how, in the week before the attack, Daniel Grogan had become increasingly jealous of Jay – who was dating his ex-girlfriend – and had made repeated threats to kill him. He had also attacked Jay’s girlfriend two days before his death.
At around 21:50hrs on 11 December 2018, Jay had travelled with some friends and his girlfriend to meet Daniel Grogan at Alwold Crescent, SE12. Their intention was to stop Daniel from threatening and harassing Jay’s girlfriend.
When they arrived, Jay and his friends were ambushed by the defendants, who came out of an address in Sibthorpe Road armed with knives, hammers, wood and an axe.
Jay was stabbed along with another 18-year-old man (Victim 2). The two victims were taken to a south London hospital suffering from stab injuries.
Despite the work of the emergency services, Jay died in hospital at 22.34hrs that evening. A post-mortem examination gave the cause of death as a single stab wound to the chest. He was stabbed a further two times in the legs.
The second victim was subsequently discharged from hospital.
Detectives from the Met’s Specialist Crime command launched a murder investigation led by Detective Chief Inspector Simon Harding.
Officers seized CCTV footage and conducted an extensive forensic search of the area. As a result of the search, two hammers, a block of wood and a knife were found.
