WACO, Texas (AP) - A minister's former mistress told a jury in Waco today that he admitted killing his spouse in 2006 -- by drugging and smothering her.
Vanessa Bulls says Matt Baker had talked about killing his wife and making it look like a suicide.
Baker is on trial for murder -- but he has claimed his wife was depressed and committed suicide.
Bulls has been granted immunity from prosecution.
Bulls told jurors she did not help Baker plan the killing or participate in it, but was afraid to report him because she feared being arrested.
She also says she was afraid of exposing the affair that she says began about two months before Kari Baker's 2006 death.
Bulls called Baker as "a manipulative liar."
Defense attorney Guy James Gray told jurors last week that the death, initially ruled a suicide, only became a murder case after authorities found out about his affair.
