BRIDGEPORT — Testimony is set to begin Wednesday morning in the trial of an undocumented immigrant accused of fatally stabbing his girlfriend, seriously wounding her best friend and fleeing the state with their 6-year-old daughter.

In front of a 12-member jury and state Superior Court Judge Kevin Russo, Oscar “Ziggy” Hernandez is facing charges of murder, attempted murder, first-degree assault and risk of injury to a minor.

Hernandez had been living with his girlfriend, Nidia “Yubi” Gonzalez, 26, and their 6-year-old daughter Aylin, in a small, two-bedroom basement apartment on Greenwood Street when, in the early morning of Feb. 24, 2017, police said Hernandez, in a jealous rage, fatally stabbed Gonzalez and wounded her friend.

Hernandez fled with his daughter, leading police on a three-state pursuit before Hernandez crashed his vehicle in central Pennsylvania.

Hernandez, who worked at a Stamford deli, was convicted of choking an estranged wife in their apartment in 2008 on Stamford’s East Side.

Hernandez was deported in 2013; authorities said he illegally returned to the U.S.

If convicted, Hernandez could be sentenced to more than 100 years in prison.
