The mum of missing studenthas been filmed walking and discussing the route he was last seen taking in Bristol before he disappeared.
Catherine O'Sullivan is filmed talking about the evening her son vanished after leaving a party more than six months ago. Multiple searches by police and organised privately by the family have failed to yield significant answers - and his disappearance remains a mystery.
Jack, 23, was last seen at 3.15am on Saturday March 2 in the area of Brunel Lock Road/Brunel Way, in Bristol. His mother has been filmed on the route CCTV showed him taking that night - with the videos posted on the 'Find Jack' campaign page.

Part one of the video is titled: 'Jack went to a party on Hotwell Rd Friday March 1st. He left the party at 2:53AM Saturday March 2nd. The following film picks up Jack's route from Macadam Way south of Cumberland basin.' His mum says: ''So, what we do know is that he's come along past the front of the restaurant and then he's carried on and then cut through these pillars, and then he's walked possibly through this car park or possibly on the road.
''He's picked up again then on the Create Centre building on the corner over there, there's a camera. That road was open, and this is where there was a stationary car after Jack had left this area. It just stopped in the middle of the road over there. This was about 10 or 15 minutes after Jack was seen. By then, he could have easily been picked up over there and brought back round here.
''There's a camera, which is on the corner of that building (Create Centre) below the red brick. That's what picked him up going around this corner. What we can only assume is that he carried on through here. There are lots of cameras all over here, but not all of them are working."
She added: ''We've got images of Jack and he's passing these railings coming in this direction. This is the point now where we know that he's here somewhere, but we don't see him again for about eight minutes. We don't believe he's gone down there, because there is a camera at the end of there, and that doesn’t pick up anything.
''I haven't been able to physically view it myself. So much has been missed that unless I can see it with my own eyes… When it is very dark, it's really poorly lit here (by canal under motorway bridge). It is quite creepy.
''As you go around this corner, it's really not pleasant. I never felt this was a possibility (the canal) because you'd have to get other this (the fence) to fall in. It's very dark, and when it is dark, it's pitch black here. When we've come down here at one in the morning, we've brought torches or used our phone torches.
''He's then entered the car park, but we can't be certain whether it was from this end. He could have walked along here and then thought 'hang on, this is wrong' and then gone back on himself, hence the time – obviously there was this lapse of time. I don't believe he was jut sitting still for that time, I think he was on the move, looking for a route out.''

Pointing out that Jack approaches an area with no railings, Catherine continues: ''There are so many potential issues....to have been to a party and didn't know where he was and was drunk and in the vicinity of water… He's now crossed over from Hotwells, over the wooden bridge by the pump house, and he's come down where the Lockside restaurant is.
''If he hadn't chosen to be on the pavement side, he could have chosen to be on the Lockside of that. He's evaded a lot of potential issues. For me, I'm thinking he's cleared this, he's cleared that, and all this time, he seems to be getting himself out of scrapes, rather than more into it. To put himself up on that bridge…
''The end point of it, the police are thinking, is that he ended up in the water, but he'd have done a hell of a job getting there. Something like this (shrubbery area near canal with no railings), to me, is really dangerous, and it's pitch black normally. There's no lighting here.
''You could wander, thinking 'I wonder what's over there', and you could be down the side in an instant. The next time he's picked up is entering this car park from this angle. He's walked through here and passed these pillars. There weren't as many vehicles as there are now. These are the council vans.''
After approaching an area where two council vans were seen parking on CCTV, Catherine says: ''There's a part of this that's a holding bay for council material. That is the security shop over there, and it's their cameras that picked him up.
''They've got him walking through here and walking straight across here and up onto the grass. This used to be more of a flowerbed, and I can see him moving to the side to avoid it. Then he's walked into the middle and we don’t have any more footage because that's the angle that it cuts out. In my mind, down there is a very unsavoury area (second poorly lit bridge area). It's pitch black.
''He's off camera for about eight or nine minutes, and we can't be exact about what happened during that time. Has he unfortunately stumbled across something he didn't need to stumble across? Because this is not a very nice area.
"He must have just thought 'how the hell am I going to get out of here?'. Jack is liable to have climbed over the fence, he's fit and able and could have given it a go, but we don't know. I try to put myself there all the time – what would Jack think, what would he have done, and what direction would he have taken? I never once considered he would be heading back into Hotwells.
''I can't be 100 per cent sure why I can say that, but my gut feeling when I stood over there, was that he's gone up and tried to join the road above. For a long time, we had no evidence to suggest that, and it was just me and my feeling, but then we found him on camera.
''From much later on CCTV, he's come up and followed this road all the way to the top. He's gone up on this side, because if he had been on the other side, the camera in the underground car park would have picked up his movements. At this distance, it hadn't picked anything up.
''There are some vehicles that come down this road at night time. Not many, but some cars would have gone past. My gut feeling is that he's continued to the top of this road, and then tried to make a decision on what to do. He's off camera for about five minutes.
''But then when you do get to the top, the traffic is constant. There is a stop over there with lights, and the lights were in action, you can see that on the CCTV. I'm thinking there must have been people stopped at those lights at some point – did anyone who was stopped see something? Now, we know he’s got to about here (motorway), and it's another what happened next. He's off camera, and then he remerges. There's nowhere for anyone to stop for him, there's no natural stop here.''
It is said Jack then turns back from the road home towards Bristol. His mum comments: ''From this point now, Jack comes back into camera. As he's headed along here, that camera has picked him up, and he's definitely on this side of the road and not that side (facing away from the traffic).
''From this point, when he goes off camera, I know that 15 vehicles passed him. I've counted them when I've watched it. I feel like this is quite an unusual place for a pedestrian in the daytime, never mind half past three in the morning. We've been constantly appealing for someone to come forward.
''He goes off camera pretty much as the bridge ends. It was a particularly cold night and it was sleeting – the ground was nearly white, whether that jolts someone's memory. The stretch of road that we would be following on is called Bennett Way, and we don't know how Jack got to the end of Bennett Way, but we certainly know he's walked back up it.
''One of the questions that we can't get to the bottom of is how did he get to the end of it? Potentially, he'd be following this path, which I think is the most likely. He's walking in a straight line, with a sense of quite purpose.
''His movement is such that he's not stopped, and even when he's out of sight for a moment, if you keep time with him, he reappears. I saw that his movement was quite consistent.
Speaking about phone calls Jack made on the night, Catherine explained: ''What we know is that at 3:24, he made a call to a girl that was at the party. That would completely fit with him being up on the bridge. At 3:35, she called him back in this area, maybe even this exact spot (bottom of Bennett Way), and he answered the phone and said hello, even though the call remained open for another 58 seconds.
''The person that was on the other end of the phone didn't hear any noise in the background. She continued to speak, but Jack didn't answer. He just said 'hello'.
''When he's walking up this section of the road, it's a very consistent walk and it doesn't look like he's come off the path. The footage is from the camera over there at the traffic lights.
''When we get to the top, what we don’t know is what happened next. I can't see how somebody hasn't spotted him. That corner is fairly well-lit, and we know that there's so much traffic, even at that time in the morning.
''Whether he's gone back down into Hotwells, or he's tried to cross two lanes of fast moving traffic, or gone back on himself, which we really don't believe to be the case, then it's impossible for someone not to have driven past him.
''My plea is if you've seen him, it's so important for us to know what direction he was going in. It could potentially change everything for us. My belief is that he's continued down into Hotwells. If he'd stayed on this path, that's probably the safest thing he could have done.
''My belief is that he'd attempted to start a journey home, but because there was no option for a taxi to pull in, then I think he would have gone back to what he knew. It was quite normal for Jack to take a taxi back from Hotwells.
''What we do know is, after the phone calls, his phone had various activity. A data usage at 4:39, which is another hour after he was seen at this point. At 5:40, his phone location was suggesting that he was two or three roads from here on Grampy Hill, at an address. We're told that that was approximate, but I don't understand why an approximate address would have a house number, and that's a question we haven't been able to have answered.''
