For 10 weeks, Ben O’Sullivan’s days have been spent visiting a Bristol flyover looking for his brother.

Jack hasn’t been seen since 2 March, when he was pictured walking across a grassy area near Brunel Lock Way in the Hotwells area.

Ben’s trying to imagine what Jack, who’s four years younger, might have been doing and where he might have gone after leaving a party in the early hours.

“We know he went to a pub in town and then went on with a few friends to house party in Hotwells,” Ben, 27, tells BBC Newsbeat.

“There’s been a lot of unanswered questions since then.

“But going down there has provided us a way of trying to get to the bottom of everything.

“So this has become a daily routine almost.”

The last confirmed sighting of the 23-year-old student was at 03:13 GMT.

But a couple of weeks ago, there was a possible breakthrough when CCTV picked up a figure walking over Plimsoll Bridge about 10 minutes later.

Then, again, walking along Bennett Way at 03:38.

Avon and Somerset Police told Newsbeat these were “likely sightings of Jack”.
