(WJBK) - A New York woman convicted of killing her baby in the 1980s -- who is also suspected of killing seven of her other children -- is getting out of prison.
Marybeth Tinning, 75, has been locked up since 1987, when she was sentenced to 20 years to life for killing her 4-month-old daughter Tami Lynne. For the past decade, she's tried for parole multiple times. Earlier this month, she was finally granted parole on her seventh attempt.
Tinning has been in prison for 31 years after being convicted of her daughter's death. The Daily Gazette reports the baby was smothered to death.
Tinning's case gained national attention because all nine of her children died young between 1972 - 1985, which is when her ninth and final child, Tami Lynne, died. Eight of the children died of suspicious circumstances, and none lived beyond the age of 4. Authorities believe the couple's first child died of natural causes.
At her first parole hearing in 2007, Tinning denied any involvement in Tami Lynne's death. She admitted it, though, at her second appearance and consistently in appearances afterward.
"After the deaths of my other children ... I just lost it," Tinning reportedly told the board Jan. 26, 2011. "(I) became a damaged worthless piece of person and when my daughter was young, in my state of mind at that time, I just believed that she was going to die also. So I just did it."
As for the other suspicious deaths, she continued to deny harming any of the children.
Her husband, who is still living, has reportedly stood by her through her trial and her prison sentence. It's expected his residence will be acceptable for Tinning to the parole board.
A release date for Tinning hasn't been set yet.
