The last time Anthony Aiello spoke to his stepdaughter, he took homemade pizza and biscotti to her house in San Jose, Calif., for a brief visit. Mr. Aiello, 90, told investigators that she then walked him to the door and handed him two roses in gratitude. But an unnoticed observer in the house later revealed that their encounter ended in murder, a police report said. Five days afterward, Mr. Aiello's stepdaughter, Karen Navarra, 67, was discovered by a co-worker in her house with fatal lacerations on her head and neck. She had been wearing a Fitbit fitness tracker, which investigators said showed that her heart rate had spiked significantly around 3:20 p.m. on Sept. 8 (Warning: source may be paywalled; alternative source), when Mr. Aiello was there. Then it recorded her heart rate slowing rapidly, and stopping at 3:28 p.m., about five minutes before Mr. Aiello left the house, the report said. Mr. Aiello was arrested last week on murder charges and booked into the Santa Clara County Jail, the San Jose Police Department said. On Thursday, he will appear in court in the Hall of Justice in San Jose, according to the Santa Clara County district attorney's office.
