Dena Schlosser (née Leitner, 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 call made by concerned workers at a local daycare center who had spoken to her earlier that day.
When police arrived they saw her calmly sitting down, covered in blood, holding the knife, and singing Christian hymns.
The day after Margaret was born, Schlosser attempted suicide, was hospitalized in a psychiatric ward, and was diagnosed with bipolar disorder with psychotic features.
[8] She was found not guilty by reason of insanity and was committed to the North Texas State Hospital and ordered to go there until she is deemed to no longer be a threat to herself or others.
Davidson thought that mental illness was demonic and this belief partly led Schlosser's husband to not buy her medication regularly.
CPS said they would only allow her husband to regain custody of them under the condition that his sister live with the family, and he was required to complete psychotherapy and parenting classes.
The order required her to see a psychiatrist once a week, take medication, be on physician-approved birth control, and not have any unsupervised contact with children.
She stayed out of the public eye until 2012, when WFAA-TV in Dallas reported that she was working under her maiden name, Leitner, at a Walmart in Terrell.
