A 12-year-old who was suicidal, has killed a young woman after he jumped from a 30ft bridge and landed on her car, The Sun UK reports.

The schoolboy has suffered life-threatening injuries after the tragic incident which killed Marisa Harris, 22, of Olney, Maryland, in the US state of Virginia.

The depressed lad leapt from the overpass on Interstate 66 in a bid to end his life but crashed into the Harris’ car, reports NBC Washington.
