 However, Christopher Sean Harper-Mercer spared a student and gave the "lucky one" something to deliver to authorities, according to the mother of a student who witnessed Thursday's rampage. Authorities have not disclosed whether they have an envelope or package from Harper-Mercer, who Douglas County Sheriff John Hanlin said Saturday killed himself as officers arrived. Bonnie Schaan, the mother of 16-year-old Cheyeanne Fitzgerald, said she was told by her 16-year-old daughter that the gunman gave someone an envelope and told him to go to a corner of the classroom. The law enforcement official who disclosed the existence of the manifesto did not reveal its contents but described it as an effort to leave a message for law enforcement. The official is familiar with the investigation but was not authorized to disclose information and spoke on the condition of anonymity. Authorities say police officers arrived on the scene six minutes after receiving the first 911 call about the shooting, the Associated Press reports, and officers exchanged gunfire with the shooter two minutes later. Harper-Mercer was enrolled in the class, but officials have not disclosed a possible motive for the killings.  
 
 
 
 The family of Oregon community college shooter Christopher Sean Harper-Mercer released a statement Saturday, saying they are “shocked and deeply saddened by the horrific events,” which resulted in 10 deaths, including that of their son. The father said he had not seen his son since he and his mother, Laurel Harper, moved to Oregon about two years ago, but said there was no “disharmony or any bitterness” between him and his son.
– Details are emerging on the grisly mass murder at an Oregon college—including reports that the shooter gave one "lucky" student a message for authorities before killing nine people and taking his own life, reports the AP. Gunman Christopher Harper-Mercer handed over an envelope and said that student "'was going to be the lucky one,'" according to the mother of a student who was shot and wounded in the spree. A pastor whose 18-year-old daughter wasn't injured told a similar story, with the gunman saying, "'Don't worry, you're the one who is going to survive,'" while the grandmother of a survivor said the "lucky" student was told to stand in a corner with the package. Authorities haven't confirmed, but one law enforcement source says a pages-long manifesto has been found. The pastor, Randy Scroggins, relayed other stories from his daughter—about how Harper-Mercer told one student to beg for her life but shot her anyway, and shot other students after telling them to crawl along the floor. Scroggins says his daughter only survived because another student's blood and body was lying on top of her. "He saved my girl," he said after talking to that student's mother. "I will forever call your son my hero." Other reports have Harper-Mercer targeting students in the writing class for being either Christian or religious. Meanwhile, the gunman's family released a statement saying they were "shocked and deeply saddened by the horrific events," Time reports, and the father said a change in gun laws could prevent future tragedies, the New York Times reports.
