Woman who went missing from outside of a downtown bar was last spotted in Charlestown

UPDATE: Ambrose found alive in the Bunker Hill development.

Boston Police have released a timeline of Olivia Ambrose's movements the night she disappeared and two photos of a man they want to question about her whereabouts.

According to police, Ambrose was seen leaving Hennessy's on Union Street at 11:04 p.m. on Saturday, "with a white male who has since been determined to not be involved in her disappearance:"

• 11:42 PM: Approximately 40 minutes later, two unknown males are observed inviting Ms. Ambrose to walk with them in the area of Congress Street and State Street. One of the males appears to walk ahead while the second male (shown in the photos above) places his arm around Ms. Ambrose and directs her towards the State Street MBTA Station.
• 12:01 AM: Approximately 20 minutes later, additional video shows Ms. Ambrose being accompanied by that same male, still with his arm around her, exiting the Bunker Hill Community MBTA Station in Charlestown. The other male party is no longer observed in any surveillance video moving forward.
• 12:13 AM: Approximately 10 minutes later, Ms. Ambrose and the unknown male are observed again in the area of Green Street walking together towards Bartlett Street. A short time later, phone records indicate Ms. Ambrose’s phone was in the general area of the Bunker Hill Housing Development.

Anybody who knows how to contact the guy in the photos, or who knows anything about Ambrose's current location can contact detectives at 617-343-4248 or the anonymous tip line by calling 800-494-TIPS or by texting TIP to CRIME (27463).
