NEWTOWN, Conn. (CBS/AP) — Newtown marked the fourth anniversary of the Sandy Hook Elementary School shooting with a moment of silence on Wednesday morning.

It was Dec. 14, 2012, when a troubled 20-year-old gunman shot his way into the Connecticut schoolhouse and killed 20 children and six educators. Adam Lanza fatally shot his mother before driving to the school, and then killed himself after the rampage.

The town typically does not hold an official memorial event on the anniversary of the tragedy, but prayer services are planned for Wednesday and a counseling center will be open for extended hours.

First Selectman Pat Llodra asked town employees to refrain from doing any work, including answering phones, between 9:30 a.m. and 9:45 a.m. to mark the time when the shootings took place.

Nicole Hockley, who lost her son Dylan in the shooting, told WCBS 880’s Peter Haskell she has yet to grieve.

“I’m not ready yet,” Hockley said. “I’m still on a path, and I will start grieving in my own time when I’m ready, a little bit at a time.”

She continued, “My way of dealing with grief is to stay very busy and try to make Dylan’s death mean something by saving the lives of others. In my opinion, D.C. is broken.”
