Dearborn police are looking for two customers who they say were inside a Family Dollar sometime before a 20-year-old store worker was killed and his co-worker went missing.
Dearborn Police Chief Ron Haddad said said investigators want to speak with the two females customers who were in the store Monday at about 7:25 p.m. and 7:35 p.m.
Haddad said the women are not being accused of anything, but are only being sought for informational purposes.
Haddad said there's still no motive for the crime.
Man dead, woman missing
Joe Orlando, 20, was found shot dead Tuesday morning at the store off Michigan Avenue.
His 20-year-old co-worker, Brenna Machus of Romulus, is missing. The two were working together Monday night.
Police have released a 17-second surveillance video of a person of interest waving his arm as he entered the store Monday night with a hood over his head. His face isn't clear in the video.
Crime Stoppers is offering a $2,500 reward for information that leads the arrest of whoever is responsible for killing Orlando.
There is an $11,100 reward being offered for information that leads to the person who abducted Machus.
All tips are anonymous and can be called into 800-SPEAKUP.
