It's been 10 years since the worst act of domestic terrorism was committed at the Alfred P. Murrah Federal Building in Oklahoma City. The bombing took place on April 19, 1995. Today, 10 years later, the pain is still real for those who lost loved ones in the bombing and those who's lives are forever altered by it.

Today, a moment of silence was observed at the site, now known as the Oklahoma City National Memorial. People brought flowers and teddy bears to remember loved ones and friends and a moment of silence was observed at 9:02 AM, the time Timothy McVeigh's truck bomb exploded and destroyed the north side of the building.

McVeigh was executed for his crimes on June 11, 2001. His coconspirator, Terry Nichols is serving multiple life sentences and will almost certainly spend the rest of his life behind bars.

Among those scheduled to speak at the event are former President Bill Clinton who was in office at the time of the blast and Vice President Dick Cheney.

Jenny Parsley, who had a dentist appointment that faithful morning which saved her from being trapped in the blast, planned to attend the memorial service today. 'I knew most of the people killed,' Parsley, 57, told the Associated Press. 'I lost a lot of good friends, too many.'

Juanita Espinosa was attending to remember her 2 1/2 year old cousin, Zackary Chavez, 2 1/2. 'They found his head one week, and his body another week,' she said. 'It's still too much to think about.'

10 years after the bombing claimed 168 lives, the pain is still real. But life does go on. Larry Whicher, 44, who lost his brother in the bombing, explained, 'You learn to accept it. You can't change it, so why carry that bitterness for your entire life?'
