The lawyer for Adele Sorella, a Quebec mother accused of killing her two daughters, is questioning the work of investigators who analyzed the crime scene.

Gilles Chamberland told the court he didn't believe Adele Sorella was faking amnesia when she told the court she didn't remember much about the day her daughters Amanda and Sabrina De Vito died.

Adele Sorella is testifying in her own defence for a second day at her first-degree murder trial in the deaths of Amanda and Sabrina De Vito.
