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. The operator testified that she confessed to her and that the gospel song "He Touched Me" played in the background. When police arrived they saw her calmly sitting down, covered in blood, holding the knife, and singing Christian hymns.

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