Video Shows Last Known Moments Marissa DiNapoli Was Seen Alive — Boyfriend Spotted Carrying Plastic Bag the Next Day

In her final known moments, a California teen was seen on surveillance footage leaving a home with her ex-boyfriend, who is now charged with murder in connection with her death. 

Marissa DiNapoli, 18, was reported missing on June 30, the Morgan Hill Police Department said in a statement.

Police promptly named Martin Mendoza a person of interest in her disappearance. He was identified by The Morgan Hill Times and ABC 7 as DiNapoli’s boyfriend at the time she went missing.

During the search for her, DiNapoli’s body was found on July 2, the Morgan Hill Police Department announced last week.

Mendoza, 21, was arrested while allegedly trying to re-enter the U.S. through the Mexican border, the Morgan Hill police announced on Monday, July 8.

Now, Ring camera footage obtained and shared by KSBW shows DiNapoli in her final known moments.

In the video — which according to the outlet, is from Mendoza’s home outside Morgan Hill — DiNapoli is seen walking down the stairs, carrying clothes in her arms, with Mendoza next to her as he talks to her. 

The nature of the conversation is unclear but the two look serious as they speak. At one point, as the two walk towards the door, DiNapoli briefly glances up at Mendoza before he opens the door to let her out. 

The video is timestamped at 9:45 a.m. on June 29 — the day before the teen was reported missing. 

In another piece of Ring footage KSBW reports was taken the following day, Mendoza is seen running down the same staircase in a white hoodie, carrying a teal plastic bag in his hand.
