Man convicted in stray-bullet killing of Puerto Rican Olympian’s mom in her Connecticut home

A Connecticut man has been convicted of murder in the stray-bullet killing of the mother of a two-time Olympian rifle shooter from Puerto Rico. A jury found Franklin Robinson guilty on Friday in the death of Mabel Martinez Antongiorgi. The 56-year-old was in her sewing and crafts room in Waterbury when a bullet flew through a wall and hit her in the head on April 9, 2022. Martinez Antongiorgi’s daughter, Yarimar Mercado Martinez, competed for the family’s native Puerto Rico at the 2016 and pandemic-delayed 2020 Games. Robinson’s defense questioned the credibility of a key witness.
