A man reported missing in Oklahoma is the former business partner of Belmont County business owners who were murdered in 2021.

The Pottawatomie County (Oklahoma) Sheriff’s Office is asking for the public’s help in the search for Andrew Isaac Griffin. He was reported missing Friday after leaving a relative’s home to report to work in Texas.

Lisa Strussion Ballog, sister of the late Thomas Strussion, confirmed Tuesday that Griffin was her brother’s partner in the Elm Grove Salsa Joe’s restaurant business.

Thomas and Angela Strussion were found dead inside their home on Trails End Drive, Belmont, after a structure fire was reported there early on Sept. 21, 2021. Days later, Belmont County Sheriff David Lucas announced that their deaths were the result of a double homicide.

The National Missing and Unidentified Persons System, via its website at namus.gov, describes Griffin as a 30-year-old white man, 5 feet 11 inches tall and weighing 200 pounds. He goes by the nickname “Drew” and has short, brown hair, blue eyes and a red beard.
