"The black SUV, later discovered to be a Ford Escape, became a vehicle of interest after a witness tipped police off that they had seen the vehicle twice near the scene of the murder.
The witness saw the vehicle two times. Around 12 p.m., the witness saw that Colon-Ortiz's vehicle appeared to be broken down, as he was standing near the car with the hood up. Then, at 2:05 p.m., the witness saw Ortiz and his vehicle again, this time with the hood and all the doors closed."
"Prosecutors also revealed that Marcotte's phone was turned off the day of her death. A check of the cellular provider shows that Marcotte's phone was
shut off after 2:11 p.m.
