When Sharon Lees' son David left a psychiatric unit, she said she warned staff he was too unwell to come home.
Ten days later, he stabbed a man to death who was out walking his dog because of "the voices in his head".
Sharon is demanding a public apology from Hywel Dda health board for both her son and the family of the man he killed, Lewis Stone, saying it "could [and] should have been prevented".
Hywel Dda said confidential information prevented it publishing its report.
Sharon raised her son David Fleet in the seaside town of Borth, Ceredigion.
"David loved being on the beach," she said.
"Growing up in Borth was really good for him. He was very quiet, would easily get lost in the crowd."
