The father of a 6-year-old boy killed in the Sandy Hook Elementary 

School shooting testified Tuesday that conspiracy theorist Alex Jones made his life a "living hell" 

by pushing claims that the murders were a hoax involving actors aimed at increasing gun control.

In more than an hour of emotional testimony during which he often fought back tears, 

Neil Heslin said he has endured online abuse, anonymous phone calls and harassment on the street.

Heslin and Lewis are seeking at least $150 million in the case.

"Today is very important to me and it's been a long time coming ... to face Alex Jones for what he said and did to me. 

To restore the honor and legacy of my son," Heslin said.

An apology from Jones wouldn't be good enough at this point, he said.

"Alex started this fight," Heslin said, "and I'll finish this fight."
