The investigation continues into the death of a man involved in a domestic violence incident with a sibling.

After a lengthy standoff, a man was found dead inside home

Around 6 PM Thursday night, Benton County Deputies were dispatched to an area between Benton City and Prosser, near District Line Road by the Old Inland Empire Highway.

The BCSO says a domestic violence assault was reported, an adult male threatened his adult sister with a firearm, threatening to kill her. He also allegedly kept her from leaving the home for several hours. Authorities said the man was also a convicted felon, and not allowed to possess a gun.

After the Tri-Cities SWAT Team was activated and the house surrounded and secured, multiple attempts were made to contact the man, and urge him to surrender, but with no success.
