Jurors in Scott Peterson´s murder case today saw images of Laci Peterson alive, smiling and joking with friends at a videotaped gathering in the Petersons´ home.
The home video was seized during the investigation.
Also Thursday, the lead detective assigned to investigate Laci´s disappearance testified that police followed a number of leads in the case before arresting her husband.
They even looked into the possibility of a serial killer.
Modesto Police Detective Craig Grogan told jurors that about week before police arrested Scott Peterson, he searched a federal serial killer database for possible clues in Laci´s disappearance.
Grogan said no links were found.
