A reward of up to £20,000 for information leading to the identification, arrest and prosecution of the person or persons responsible for the murder remains in place.
Officers were called at approximately 23:10hrs on 20 October 2012 to Montagu Road at the junction with Goodwin Road, N9, following reports of an assault.
Teon Palmer, 28 (07.07.84), from the Lower Edmonton area, was pronounced dead at the scene.
A post-mortem examination gave cause of death as a single stab wound to the chest.
It is believed that a car belonging to Teon had all four tyres slashed in the moments leading up to the assault. A number of males, described as wearing hooded tops or jackets, were seen making off from the location.
Detective Inspector John Marriott, from the Homicide and Major Crime Command, said:
“Although four years have passed, we remain committed to finding those responsible for Teon’s murder.
“I strongly believe that there are people, who were not there that night, who know who stabbed Teon. I would urge them to contact us.
“It is also possible that allegiances have changed, and that someone, who may not have wished to speak with police at the time, may now be encouraged to do so. A substantial reward remains in place.
“Teon’s family deserve to know what happened. I would ask anyone who is yet to speak with us to contact the incident room.”
Anyone with information is asked to contact the incident room on 020 8345 1570; if you wish to remain anonymous call Crimestoppers on 0800 555 111.
Officers arrested four men in 2012 in connection with the murder investigation but they were all released with no further action.
