The murder trial is scheduled to begin for a man charged in a 2013 cold case involving a 94-year-old victim.
Jury selection for Robert Hashagen's trial will begin at the Oklahoma County courthouse at 9 a.m. Monday.
Hashagen was arrested back in 2017. Investigators say DNA evidence linked him to the 2013 murder of 94-year-old Evelyn Goodall. Hashagen has since been charged with first-degree murder.
In 2013, police did a welfare check and discovered Goodall had been assaulted during a break-in. She later died at the hospital.
Doctors confirmed that her death was from multiple blunt force traumas.
Four years later, detectives discovered new leads in Goodall's case.
Investigators say Hashagen lived two doors down from Goodall. They used DNA evidence to connect him to the 2013 break-in, and also a 2010 break-in at the same home.
He is a former CLEET certified officer who worked for the University Hospital Police Department in the 80s.
When Hashagen was finally arrested in 2017 he denied killing Goodall but did admit to taking methamphetamine.
