Blanchard Police reveal they are now searching for two key pieces of evidence owned by the man shot dead in a December 31 home invasion.
Investigators say they are searching for Justin Martin's lap top in addition to his cell phone.
"The lap top could contain may things. A lot of people use Facebook, they use instant messaging, they use contact information, address books, things such as that," said Detective Dan Huff.
Police were led to believe the phone and lap top were in the truck used during the home invasion, but were not found during a search of the vehicle.
Police will not say where they think the items may be, but are confident they will get them.
Martin was shot dead by Sarah McKinley on New Year's Eve when he stepped into her Blanchard home.
