OKLAHOMA CITY - An Oklahoma City judge has set a trial date for a Tulsa dentist accused of killing his girlfriend's baby last year.

During a hearing on Wednesday, Bert Franklin learned his trial is scheduled to begin on September 25th.  

Police say surveillance video from inside the mother's home shows Franklin slamming 19-month-old Lincoln Lewis to the ground.

Lincoln died of a skull fracture.

Franklin is also facing a charge of fraud filed in Tulsa.
