He had suffered from a mental illness, a condition that separates him from reality,   3  him to live within his own   4   . That day his thoughts were set on climbing to the top of that tower, touching the sky and feeling what it was like to   5   .

When secured with a safety line, the brothers and their rescuers were carefully lowered to the ground, the crowd below burst out  19   . They witnessed the   20  of a 17-year-old boy named James.
