The detective leading the Jon Casey murder investigation says police are working on some “good leads” but are still in need of new witnesses to come forward with information.
The 35-year-old father-of-two from Ecton Brook, was found with stab wounds shortly before 5.30pm on January 16, close to the Lazeez restaurant in Barrack Road.
He was taken to Northampton General Hospital but died a short time later.
Detective Inspector Mark Brayfield, from the East Midlands Specialist Operations Unit Major Crime Team, said: “We are continuing our investigations and are working on some good leads, which we believe may identify the offenders.
“We are also continuing to search the Barrack Road and Semilong areas of Northampton in our work to locate the murder weapon.
“Despite this progress, I would appeal to people who were in the Barrack Road area when Jon Casey was killed to come forward.
“This was a busy time of day with many people on their way home from work, so we know there are a lot of people who will have seen what happened.
“I would urge them to come forward because any piece of information they have, no matter how small, could be vital to solving this case.”
It is believed Mr Casey may had been involved in an altercation with two black men before he was found in Barrack Road.
As the altercation spilled out onto the road, it is believed a number of cars had to swerve out of the way close to the old Royal Mail sorting office.
An inquest into the death of Mr Casey was opened and closed at Northampton County Hall on Wednesday morning. The official cause of death was given as “stab wounds to the chest” and the inquest will resume later in the year.
Officers would still like to speak to anyone who saw Mr Casey in the Semilong area at around 5pm on the day.
Witnesses or anyone with information about this incident is asked to call the police on 101 or Crimestoppers anonymously on 0800 555 111.
