Investigators believe last month's slaying of the 78-year-old may have resulted from a home invasion robbery. They issued an alert earlier this month, seeking any of his jewelry that may have been purchased or sold by pawn shops, the Glendale News-Press reported.
Joseph Gatto was an artist and craftsman who created ornate, custom-made jewelry such as rings, bracelets, pendants and necklaces, using precious metals, stones, bone, ivory, porcelain, glass, wood and Egyptian scarabs.
The elder Gatto engraved many of his pieces with his initials and name 'J A Gatto' along with a circular design, according to a department press release.
Anyone with information is asked to LAPD detectives at (213) 486-6890.
[For the record, 5:30 p.m. PST, Dec. 30: A previous version of this post and a previous headline said the alert was issued by police on Saturday and that it was the second of two alerts released. There was only one alert, and it was released earlier this month.]
