A Michigan mother vanished on April 26^th.  Jessica Heeringa was working the nightshift alone at an Exxon Gas Station. The 25-year-old disappeared leaving behind her purse and keys. No money was stolen from the gas station and no sign of Heeringa has been seen since.

Police have released a sketch of a man they are looking for. A witness says this man was seen pulling into the gas station in a silver minivan. Surveillance tapes show a minivan driving off from the gas station but police can’t tell who is in the car.  Police believe Jessica may have known her abductor and that person knew she would be there alone.

The former cop accused of killing his wife and trying to make it look like a suicide continues his shocking testimony.  Brett Seacat told jurors today that his wife Vashti was having multiple affairs, and even said that she had tried to kill herself several times before.  CNN correspondent Ted Rowlands, in court today, tells Jane how Vashti's family reacted to today's testimony.  Then Jane and a panel of experts discuss whether it was the right decision for Seacat to take the stand.
