A victim of the Denver shooting is lucky to be after alive being hit by a shotgun blast during the attack that killed 12 people last Friday, NBC news reports.

Three pellets struck 22-year-old Petra Anderson's arm and one went through her head but missed the brain's many blood vessels and key sections controlling vital functions.

Her neurosurgeon, Dr Michael Rauzzino said: "I would say this is definitely a miracle.

"If the pellet had wavered a millimetre, really in any direction from what it actually took, then she would have likely either died or been severely injured."
