The mother of a severely autistic man who fell to his death after leaving a secure care home in Kent has said she is "truly heartbroken".
Christopher Wakeman, 23, died last November after falling 25ft from a road bridge above the A249 near Bobbing.
His mother, Catherine Butters, said: "I would like to see that the care home doesn't let it happen ever again to anybody else."
ACH, which runs the care home, said an inquiry was under way.
Mr Wakeman was a resident of Byfield Court in Bobbing, which provides residential support for people with learning disabilities.
Mrs Butters said: "I'm very angry that he was able to get out by himself because I'd put my trust in the home to keep him safe.
"I'm truly heartbroken, all my family are, and I don't think we'll ever get over losing Christopher this way."
In a statement, ACH said: "We extend, once again, our deepest sympathies to Christopher Wakeman's family following this tragic accident.
"Unfortunately, ACH is not permitted to make any further comment at this time due to the matter being the subject of an open safeguarding inquiry.
