The Brief Prosecutors have charged 65-year-old Edward Russell Jr. with the 2001 murder of Tonya Renee Armstrong in Gary. Armstrong’s family says a Hobart police detective helped solve the case after Russell was linked to four other Indiana killings. More than 25 years after Tonya Renee Armstrong was found stabbed to death inside a Gary apartment building, prosecutors have charged a man with her murder. According to prosecutors, Armstrong was killed inside an apartment building on East Fifth Avenue. Armstrong’s family said they had nearly lost hope after years without significant progress from the Gary Police Department.
