TULSA, OK -- The murder trial of Marquis Bullock continued on Tuesday.  One witness was on the stand the entire day.  He was one of the lead detectives on the case who was assigned to investigate the disappearance of 13-year-old Cori Baker.

If there was a theme for the prosecution's case on Tuesday, it was lies, lies and more lies.  They say Marquis Bullock gave police four different versions of what happened to Cori Baker on November 7, 2009.

They say first, he insisted he never picked her up from school that day, but after confronted with videotape of his car and witnesses who saw him, he later admitted he did.  They say he then said he and Cori rode around for awhile, and then he dropped her off near her home. 

His third story was he took her to the Arkansas River and while horse playing, she fell in and drowned.

His final story was that after he picked her up from school, her oldest sister took her somewhere, but he didn't know where.

Bullock's attorney hammered the point that no blood was found on Bullock's clothes or in his car.  She also pointed out the videotape of the interview where Bullock said Cori drowned, was erased by a detective.

Police say it was an accident.

The case could go to the jury on Wednesday.
