IHIT took over the investigation and said Thursday that 35-year-old Yang “Christopher” Liang has been charged with second-degree murder.

“As the parties were known to one another, investigators believe this may have been a tragic incident of intimate partner violence,” Cpl. Esther Tupper of IHIT said in a statement.

Investigators said last week that two people were arrested at the scene. IHIT confirmed Thursday that only one person was charged.
