Chilling details are emerging about the horrific scene inside an Oregon community college classroom as gunman Christopher Sean Harper-Mercer shot and killed his victims.

The father of 18-year-old Lacey Scroggins — who survived physically unhurt — says his daughter heard the gunman tell one victim he would spare that person's life if the student begged then shot the begging victim anyway.

Lacey Scroggins' father, Pastor Randy Scroggins, told The Associated Press his daughter also told him about students being ordered to crawl to the middle of the room and the gunman shooting them.

Pastor Scroggins said his daughter survived because she was lying on the floor and partially covered by the body of a fellow student. Scroggins said the gunman thought his daughter was dead as well.

Lacey Scroggins told her father the gunman stepped over her and shot someone else.

The father of the gunman who killed nine people at an Oregon community college says he had no idea his son had guns. He also believes gun laws should change.

Ian Mercer, the father of gunman Christopher Sean Harper-Mercer, lives in California. His 26-year-old son had been living in Oregon.

Ian Mercer told CNN on Saturday that he is struggling to understand how and why the shooting happened and that he was stunned to learn his son had accumulated so many guns.

Authorities say Christopher Sean Harper-Mercer had 14 guns and took six to the campus.

Ian Mercer also told CNN his heart goes out to the grieving families.

The father says there is talk about gun control after shootings such as the one in Oregon but nothing is done.

Conflicting reports are emerging about whether the gunman who killed nine people at an Oregon community college singled out Christians as his victims.

Janet Willis, grandmother of wounded student Anastasia Boylan, said victims who identified themselves as Christian were shot in the head.

However, the mother of another wounded student said the gunman asked his victims if they were religious but did not specifically target them if they were Christians.

Stephanie Salas, mother of 18-year-old survivor Rand McGowan, said the shooter asked about religion to let his victims know they were about to "'meet their maker.'"

Police have not disclosed any details about a possible motive. Gunman Christopher Harper-Mercer died following a shootout with police.
