What about 911 ?Yeah jumped into a river once as a dare on a stag do years ago having been drinking all night. Any half decent swimmer would swim to safety.
You also have to remember that the water in the canals is calm water, so it would be easy to swim in.
All I'm saying is if this bloke has attacked 28 people, then there would be survivors, especially as none of the victims had any signs on them that they'd been attacked.
Your not going to push 28 pissed people into a canal and all 28 die.
It's hard enough to get away with murder once, with how advanced forensics have become and the fact there is CCTV everywhere, so how has this guy managed to commit the perfect murder 28 times, without leaving any possible clues.
It just doesn't add up I'm afraid.
Anything suspicious there ?

"locked" and the article was about canals, nice one
