Mother of missing student Jack O'Sullivan says she has 'no support from the authorities that should be helping' to find him

The mother of missing student Jack O'Sullivan claims her family has had 'no support from the authorities that should be helping' to locate him.

Jack, 23, vanished without trace after being last seen at 3.15am on Saturday, March 2 in the area of Brunel Lock Road/Brunel Way, in Bristol after leaving a house party. 

His mother Catherine O'Sullivan has said she will 'not give up' until she gets answers over her missing son Jack.

The family have previously criticized the police for their investigations into Jack's disappearance and want the police to release Jack's phone data which she believes could help unlock the mystery of what happened to him.

Catherine has now posted about her frustration with the police on the 'Find Jack' Facebook page today.

She wrote: 'Jack is one of the most important things in my life and I will not give up until I get an answer.

'We have no support from the authorities that should be helping so it's totally down to our family, friends and the public to keep up the fight.

'Please, please continue to share our plea of help to find Jack.

'Many thanks, Catherine (and all at team Jack) Any information can be sent to [email protected].'

The University of Exeter graduate, who had moved back to Bristol for the law course, went to a party on Hotwell Road, but at one point tumbled down the stairs and hit his head.

When a random partygoer joked about him having too much to drink, Jack shoved him in a brief clash, but this did not go further.

Jack texted his mum at 1.52am to say he was safe and planned to get a taxi and left the party an hour later, without saying goodbye to his female friend who was having a cigarette outside. He never returned home and has been missing for six months.

Previously Avon and Somerset Police have refused to release his phone records to the family and Catherine said they have had to take legal action to gain access to the data that includes where it was last tracked.

Jack's phone account belongs to Catherine although she has been unable to access the information.

Avon and Somerset Police said it rejected the family's original approach in August - citing the Home Office Communications Data Code of Practice and General Data Protection Regulation.

Officers also said the information had not taken the investigation any further to be able to locate Jack.

But Catherine, 52, of Flax Bourton, Somerset, said she wanted to review the data as she had concerns the police might have missed something.

Her post on Facebook added: 'Any information ( however small ) may help us in our quest to find him.

'I appreciate for some this is now becoming a little boring - I get told, just except it, Jack has gone and you need to move on.

'Really - what mother on this earth would ever consider giving up on her child'.
