Waneta Hoyt

From 1965 through 1971, Waneta Hoyt of Oswego, New York killed five of her six children by suffocation. Prior to her confession to the murders in 1995, the children's deaths were mistakenly believed to have been caused by sudden infant death syndrome (SIDS). One of her children was the first in the U.S. to be placed on a breathing monitor, but the child died anyway. After her confession which she later recanted, she was convicted in all five deaths and given a life sentence.
