April Vander Linden, 39, was found shot to death in her Ponchatoula, Louisiana home on April 23, 2013, with wounds to her chest and head. Investigators located 18-year-old Ryan Pourciau hiding under the victim’s daughter’s bed in the house the next day.

Officials say the killing grew out of a troubled teenage romance. Pourciau had been the boyfriend of Vander Linden’s 16-year-old daughter; after their breakup he was arrested on child pornography charges for posting images of the girl, and Vander Linden obtained a protective order on her daughter’s behalf following threatening phone calls allegedly made by Pourciau. The relationship and those threats are described as the motive for the attack in the home.
