Prosecutors spent Monday in court laying out what Otis Howie, Jr. was doing before and after they say he repeatedly shot Robbie and Crystal Jordan outside a Monroe license plate office in November 2010.
With the clothing Howie allegedly wore during the shooting sitting on the witness stand, detectives showed the jury surveillance video from a nearby cell phone store.
The video showed a man prosecutors identified as Howie, pacing back and forth while he waited for the Jordans to leave the DMV with their nightly deposit bag.
Later, employees from a Charlotte clothing store, Sports Trax, testified about more surveillance video -- where they said Howie went on shopping spree, buying nearly $200 worth of shoes with cash.
Prosecutors also called Tanika Ingram to the stand. She's the ex-girlfriend of another suspect in the case.
She told the jury she also noticed Howie making many purchases after the date of the robbery.
She also testified that she overheard Howie in a phone conversation, where "he said he had to shoot some (expletive) and do whatever he had to do to get money."
Later, when detectives raided her home, Ingram said they found Howie's gun hidden in a stuffed animal inside her child's bedroom.
Defense lawyer Miles Helms spent most of the day casting doubt on the investigation, suggesting detectives didn't collect evidence that might point to other suspects.
Tanika Ingram is facing her own charges in connection with the case, as an accessory after the fact.
The defense pointed out that after she cooperated with prosecutors, her bond was dropped from $200,000 to $25,000, allowing her to post bail.
