A man who shot and killed his wife in Vista in an attempted murder-suicide was sentenced Wednesday to 17 years in state prison.

Bouavang Thao, now 55, and his 51-year-old spouse, Xiongvang Thao, were found shot around 6:40 a.m. on Dec. 29, 2018, at a home in the 1800 block of Hartwright Road.

Thao’s wife was pronounced dead at the scene, and Thao was hospitalized in serious condition with a self-inflicted gunshot wound. A motive for the shooting has not been disclosed.

Thao was initially charged with murder, but pleaded guilty in April to voluntary manslaughter and corporal injury to a spouse, along with an allegation of personally using a firearm.
