Early on a Sunday morning, a dog walker made his way through a local beauty spot. With a picturesque lake, a play area and plenty of ducks to feed, Clowes Park is popular with families, an oasis of calm away from a busy area of Salford.
But on that cool morning, he made a discovery which would transform a leafy retreat into the centre of a murder investigation. The body of a teenage boy was found.
He'd been brutally killed, stabbed 20 times. Around the same time the appalling discovery was made, at 7.30am on January 30 last year, Alan Szelugowski's family reported the 17-year-old missing.
