Juxtaposition: cocaine deaths / adult cot death

Sarah pointed out this recent Metro front cover to me:

Metro front cover from 27 August

The lead headline reads:
Cocaine deaths jump by a fifth


The headline above the photo of the teenage girl reads:
'Angel' who died in her sleep at 16

At first glance, Sarah assumed that the girl had died after taking cocaine. However the copy alongside the photo begins:

This is Kelly Blair, a bubbly teenager whose life was cut short when she died in her sleep. The 16-year-old, described by her parents as their 'special angel', is thought to have been a victim of adult cot death, which kills around 150 people in Britain a year.


In other words, the picture caption is entirely unrelated to the cocaine story.

Sarah would like to know whether the juxtaposition of the two stories was intentional or unintentional. I'm not sure. What do you think?
