Nearly 30 years later, Milwaukee police are taking a new look at this case. Officers have been reviewing the murder since May. They say this cold case heated up due to a discovery in another case.
When police arrested admitted sex offender Daniel Acker, investigators found Machett's name or image on one of Acker's belongings. That discovery is called a jump start in the investigation. Police are not calling Acker a suspect.
Officials are now resubmitting the DNA evidence from the Machett case hoping science will connect a murderer to an unsolved crime.
