A manhunt is underway after 18-year-old Marissa DiNapoli’s body was found in a decomposed state under a bridge near Anderson Lake County Park, days after she went missing on June 29. Her last known contact was a text to family saying she’d be staying with a friend.

Surveillance footage shows Marissa leaving a house with her 21-year-old boyfriend, Martin Mendoza — now a person of interest — on June 29. He later returned alone in her car. Audio reportedly captured Mendoza confronting her about texting her ex. Authorities confirmed the remains as Marissa’s on July 3.
