Friends of teenager Adam Pickup will go on patrol with Manchester Street Angels to mark the first anniversary of his death.
Adam, 17, from Stockport, went missing following a night out in Manchester on December 28 last year.
His body was discovered on wasteland near Deansgate Station two days later.
A campaign was set up by radio station Key 103 to recruit teams of volunteers to help make Manchester safer. Manchester Street Angels began patrolling the city’s streets on November 14.
Volunteers aim to help those who have become vulnerable through alcohol every Friday between 10pm and 2am.
Adam’s father Chris and mother Chantal Pickup have been supporting the project, along with his brother Ben.
They have set up Adam’s Christmas Angel Appeal to help raise the vital funds needed to keep the voluntary-run scheme going.
Chris said: “The public support never ceases to amaze us.
“Not only are members of the community giving up their time to go on patrol at night, we are also receiving a generous amount of donations to help support such a good cause.”
Adam’s family are also planning to release dozens of balloons at midnight outside Great Northern on Saturday December 27 to mark a year since he disappeared.
Chris said: “We want to do something to remember our son who died in such unfortunate circumstances. Had Angels been on the streets that night, things may have been very different.
“Adam’s friends who were out with him that night also want to do their bit by going on patrol a year on from when they lost their friend.”
The teams currently patrol Deansgate and Deansgate Locks, but plan to expand their patrols.
Rachel Goddard, the chair of Manchester Street Angels and a volunteer, said: “The support we have had from the police, the Manchester Pub and Club Network, and those enjoying nights out in the city centre has been absolutely amazing.
“We now have a base at the offices at Great Northern thanks to the generosity of management there and already we have helped dozens of people get home safely.”
