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, 40, guilty 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.
