Jack O’Sullivan missing – latest: Investigators probe data spike on Bristol student’s phone after disappearance

The mother of a missing Bristol student last seen after a night out says a specialist company is investigating data usage on her son’s phone after he disappeared.

It’s now been more than four months since Jack, who was 22 at the time, was seen walking home from a party in the Hotwells area of the city on 2 March, at 3.13am.

According to Avon and Somerset Police, he attempted to call a friend after the last confirmed sighting - but when the friend called back, Jack answered before the call was cut off.

Detectives also told Jack’s family that his phone had data usage equivalent to a nine-minute video between 4.39am and when the device was last active on a network at 6.44am,

Mother Catherine O’Sullivan said a replacement SIM had been created and now sent off to a cyber specialist company in Manchester to analyse usage in the hope it’ll offer clues on his disappearance.

Money for the work is partially being paid from a GoFundMe page that has raised almost £30,000, with £20,000 of it already going toward a reward for information on where Jack went.

The public is urged to contact the family’s campaign with any information on findjack23@gmail.com, or police on 101 or 999 quoting reference 5224055172.
