Day 2: New developments in alleged love-triangle murder trial

Before she disappeared in 2012, Cari Farver had been diagnosed with bipolar disorder.

Farver's mother, Nancy Raney, discussed her daughter's mental state in testimony during day two of a trial prosecutors say revolves around a "fatal attraction."

Investigators believe Farver was killed by Shanna Golyar, her rival in a love triangle. However, a body has never been found. Farver's mother said she is certain her daughter would never abandon her family and disappear on her own.

As proceedings progressed, Golyar's defense attorney, James Martin Davis, challenged investigators and pointed out the lack of a crime scene. He said: "Is there any evidence of foul play? Any evidence a crime was committed? No."

However, prosecutors allege Golyar wrote an email where she confessed to killing Farver. They also believe Golyar posed online to convince Farver's family she was still alive.

Farver's mother told the court she used to keep hope that her daughter would come home but now she is certain her daughter has been killed.
