Authorities have named the two Downers Grove residents killed Tuesday night in an apparent domestic dispute.

Dongwei Su, a 42-year-old man, and Yakun Sui, a 42-year-old woman, were found dead of gunshot wounds late Tuesday at a residence in the 6400 block of Fairview Avenue.

Police determined that the shooting occurred following an argument and physical altercation between the couple. Su reportedly retrieved a handgun and fatally shot his wife, authorities said.
