Who is Eric Harris from Columbine and what is their importance?

Eric was the son of a military father although his mother stayed home to devote her time to Eric and his brother. Eric was academically gifted and was able to charm his way through almost any situation. When Eric and Dylan were sentenced to a juvenile program, Eric set out to make them believe he was devoted to completing the program. He wrote what appeared to be a sincere letter of apology to the man who owned the van Eric and Dylan had broken into. He kept his grades up and by all appearances, had turned his life around. Eric was the more outspoken of the two and went to great lengths to leave behind detailed journals and information, apparently in an effort to explain himself. He was often with Dylan and another friend, Zack Heckler, and the leader of the three when they ran "missions," perpetrating petty mischief on the homes of those Eric chose. Eric was accused a year prior to the massacre of making threats against another classmate, Brooks Brown. Eric's father made him apologize to the Browns but thought they had blown an argument between the boys out of proportion. Eric was on a prescription anti-depressant at the time of the killings. Some people believed he'd been off his medication when he shot his classmates and committed suicide but the autopsy revealed that was not true. Eric's body was found in the library along with Dylan's and several of their victims. Information about his funeral was never revealed.
