Josif Fekete brought his three-year-old son home Sunday night after a visit, shot the boy's mother then turned the gun on his son and then himself, police said.
The 45-year-old man had been separated from his wife, Betty, for about a year. They had an ongoing custody dispute over their three-year-old, Alex.
Josif Fekete had the boy for a court-ordered visit Sunday, and brought him home about 6:30 p.m.
When Betty Fekete came down from her third-floor apartment to pick him up, her husband pulled out a shotgun and killed her, his son and himself, police say.
No charges were ever filed against either parent in the custody dispute, but Betty Fekete had stayed at a Red Deer women's shelter a few times over the past year, police say.
