Lafayette, Calif. ? The wife of prominent defense attorney and TV legal analyst Daniel Horowitz was found slain in the entryway of the couple’s San Francisco Bay area home, authorities said Sunday.

Horowitz, currently leading the defense in a sensational murder trial, called 911 Saturday evening to report that he found his wife, Pamela Vitale, dead in their home, police said.

Contra Costa County sheriff’s deputies said Sunday that the death was being investigated as a homicide. An autopsy was planned Monday to determine how she was killed.

About 20 officers and investigators from the Lafayette Police Department and the county sheriff’s department were at the home Sunday morning. They did not release any other information.

Vitale, 52, a former high-tech marketing executive, worked at her husband’s law practice, creating and managing databases.

Currently, he is defending Susan Polk, accused of murder in the 2002 stabbing death of her husband in the pool house of their Orinda home. Polk’s husband was her therapist when she was a teenager, and she claims she killed him in self-defense.
