Gatto, a retired teacher and jewelry maker who was well-known in his community, was found inside his Bright Lane home on the night of Nov. 13, 2013. He was slumped over a desk with a gunshot wound to the abdomen.
FOR THE RECORD
A previous version of this post gave the date of Gatto's death as Nov. 13, 2012. It was Nov. 13, 2013.
His death rattled the quiet Silver Lake neighborhood he had long called home, marking the neighborhood's first homicide in more than a year.
On Wednesday, Deputy Chief Kirk Albanese told reporters that detectives had recovered physical evidence connected with the unsolved case, but declined to say what the evidence was. He said investigators had not identified any suspects but believed whoever was responsible for the killing had fled the Los Angeles area.
He urged anyone with information, no matter how small, to contact police at (213) 486-6890 or anonymously at (800) 222-TIPS. The city has also offered a $50,000 reward for information in Gatto's death.
Assemblyman Mike Gatto (D-Los Angeles), who was joined by his two sisters, said his father's death "rocked my family."
In the weeks after the slaying, Los Angeles Police Department investigators issued an alert asking for information about custom-made jewelry that may have been taken from Gatto's home. The elder Gatto was known for his unique pieces that were each engraved with "J A Gatto" and a circular design.
On Wednesday, Albanese declined to say whether detectives had recovered anything from Gatto's home, citing the ongoing investigation.
Also on Wednesday, part of the 10 Freeway was dedicated in Joseph Gatto's name. The dedication ceremony was held in front of a mural of Gatto at the Los Angeles County High School for the Arts, which he helped found.
