Mother and Son take 100ft suicide plunge into river off bridge.

Detectives searching for a mother who is believed to have plunged 100ft to her death with her 12-year-old son have released CCTV footage of the pair on their way to the Humber Bridge.

Police said it was "highly likely'' that just over an hour later Alison Davies and her son Ryan died by jumping off the bridge within seconds of each other after travelling to the area from Stockport on April 12.

Poor quality CCTV footage recovered from a camera on one of the towers of the bridge showed two people climbing over the railings and falling from the footpath of the bridge into the water shortly before 4pm.

Humberside Police released images of the mother and son arriving at Hull's Paragon railway station shortly before 2.40pm and said they "looked to be fit and well and there was nothing unusual about either appearance''.

Detective Superintendent Colin Andrews said: "We are trying to piece together the last few hours of Ryan's life and need to track down anyone who may have information regarding how he and Alison got to the bridge.

"On the footage they look like a very normal mother and son combination which makes it all the more sad and upsetting that these images show them in what we believe to be the last few hours of both their lives.''

Ryan's body was found in the river at Swinefleet Haven, near Goole, nearly 20 miles up river from the Humber Bridge, on Easter Sunday, four days after the incident on the bridge.

His family said he was a "cheery, outgoing and friendly'' boy, but he suffered from fragile X syndrome, a hereditary condition that causes mental impairment.

Ms Davies, who suffered from depression, left a suicide note at her home in Stockport in which police said she made it clear she was in distress, felt she was a burden, and wanted to relieve her family of that burden.

The 40-year-old travelled to Humberside, an area where she had previously lived and still had emotional ties, with the intention of causing harm to herself and Ryan on the Humber Bridge, police said. But the note was not found in time.

Ms Davies also called 999 from the area of the bridge in a bid to ask officers to tell her mother "not to worry'', but hung up before the operator established whether it was an emergency.

I saw this on the news. She didnt sound like a good mum.

I heard the kid was pushed? :0

I don't know all the facts, but I would say that it would be extremely unfair to all judge her mothering ability right now. From all reports, she was suffering from severe depression. Any mental disorder affects your actions, and depression is one of the biggies. On top of feeling like the most worthless piece of shit, depression can also bring on a number of somatic symptoms. Loss of sleep, loss of appetite, inability to concentrate and a dramatic drop in energy levels.

So, on top of experiancing an emotional hell, this woman may have been totally exhausted, sleepless and weak. Delusions after long periods of depression are really common, and could have also had an effect her judgement.

Obviously its an awful situation, and of course I'm not condoning her taking her life or dragging her son along with her. But just passing it off as the selfish act of a bad mum would be highly naive. It is clear that nobody does this sort of thing in a correct mental state. Shit, she could've thought she was helping the kid, it could have been the ultimate act of her love for him.

she may be depressed. But he sure as hell didn't fancy jumping off the building. what do you expect?
