Dena Schlosser (born 1969) is an American woman who lived in Plano, Texas, who, on November 22, 2004, used a knife to amputate the arms of her ten-month-old daughter, Margaret, who died as a result.

>Plano police responded to a [9-1-1](https://en.wikipedia.org/wiki/9-1-1) call made by concerned workers at a local daycare center who had spoken to her earlier that day. The operator testified that she confessed to her and that the gospel song "[He Touched Me](https://en.wikipedia.org/wiki/He_Touched_Me_(song))" played in the background. When police arrived they saw her calmly sitting down, covered in blood, holding the knife, and singing [Christian](https://en.wikipedia.org/wiki/Christianity) hymns.

>Hours after her arrest, police heard her repeatedly chanting, "Thank you, Jesus. Thank you, Lord."

>She was found [not guilty by reason of insanity](https://en.wikipedia.org/wiki/Insanity_plea) and was committed to the [North Texas State Hospital](https://en.wikipedia.org/wiki/North_Texas_State_Hospital) and ordered to go there until she is deemed to no longer be a threat to herself or others. There, she was a roommate of [Andrea Yates](https://en.wikipedia.org/wiki/Andrea_Yates), a Texas woman who had drowned her five children in a bathtub.
