A young victim of the horrific Oregon college massacre successfully saved the life of a fellow student even as he lay dying from gunshot wounds, Daily Mail Online has learned.

Treven Anspach, who celebrated his 20th birthday just last month, used his dying body to cover 18-year-old Lacey Scroggins, her father revealed in an exclusive interview.

And because she ended up covered in Anspach's blood, deranged shooter Chris Harper-Mercer thought she was already dead.

Now Lacey, a caregiver at a senior living center in Roseburg, Oregon is convinced that she owes her life to Anspach, who she knew from her high school.

Anspach used his dying body to cover 18-year-old Lacey Scroggins, her father, Pastor Randy Scroggins revealed

Lacey is still too upset to tell her story personally, but her father, Pastor Randy Scroggins of the New Beginnings Church in Roseburg, said wants the world to know what happened and has given him the full details.

'She was lying on the floor with her eyes closed thinking, Oh God this is the day I am going to die,' Pastor Scroggins told Daily Mail Online as he sat inside his church.

'She opened her eyes and watched Treven's blood come under her arm. He was lying next to her after he had been shot, and he moved himself closer to her to cover her.

'The shooter came to her and yelled to my daughter 'Get up.' She says at that moment she felt frozen to the ground.

'He then looked at another woman he had already shot and who was bleeding and asked: "Is she dead," — meaning Lacey. The other woman said: "I don't know."

'Then Lacey heard him say, "She must already be dead," and he passed over her. It was because she was covered in so much of Treven's blood.'

Lacey, who has dreams of becoming a surgeon, was on her fourth day at Umpqua Community College, taking a class taught by slain professor Larry Levine.

Initially she thought the shooting was part of a drill as she recognized Harper-Mercer as a student who had been in the classroom just two days earlier.

Now Lacey, a caregiver at a senior living center in Roseburg, Oregon is convinced that she owes her life to Anspach (pictured right with his brother Cameron), who she knew from her previous high school

On the day of the shooting, Lacey, the sixth of seven Scroggins children, found herself next to Anspach (pictured with his parents Kimberly and Justin) who she knew from Sutherlin High School where she had spent three years

'She said he was the most vocal student in the class on Tuesday — he had tons of questions and answers, almost to the point of being annoying.'

The first thing Lacey heard was a pop from outside the classroom in the college's Snyder Hall. Then the shooter entered the class and fired two shots into the ceiling. At that point Lacey realized that her teacher, Levine, was down.

'She doesn't know if the bullet came through the window and hit the teacher or whether it was one of the other two shots that hit him,' Pastor Scroggins, 54, told Daily Mail Online, with tears welling in his eyes.

'He was firing at the ceiling and telling everyone to get down. Lacey looked up and saw him shoot someone and she watched that young man go down.

'She put her head down, still wondering if this is all a drill. She doesn't think it is real at this point — the class was a reading class that apparently you have to make sense of whatever it is that is happening around you, and she is thinking that this is the material for the day.

Like most people in Roseburg, Pastor Scroggins would not use the shooter's name, believing that to identify him by name furthers the notoriety he sought by carrying out the massacre, which ended with Levine and eight of his students dead and nine more injured.

'As he walks forward, Lacey realized the teacher was gone and a student was down and she knew then this wasn't a drill,' he said.

'She put her head down, lying in a prone position, her arms in front of her and her head in her arms.'

Lacey remembers Harper-Mercer picking out a student by the color of his clothing.

'She heard him say: "You in the orange shirt, stand up." She remembers him asking: "What religion are you? Are you a Christian?" and he said "Yes." She heard another pop and a thud as his body hit the ground.'

One by one, the shooter told other students to stand and he asked the same question.

If they answered 'yes,' Lacey, who had her eyes tightly shut, heard the same thud. If they answered no, she heard them scream in pain — because he only shot to injure them — and then heard the thud.

'He had one person come to the front and said: "I am not going to kill you. You are the one who is going to live today. ln my backpack there is a flash drive that will tell you about today."

'But then he shot him anyway.'

'He picked another one and said: "If you beg for your life, I will not shoot you." Lacey thinks this was a girl, and she begged for her life — and then he shot her too.'

One woman said to him: "I am so sorry for whatever has hurt you, I am so sorry about whatever it is that has happened." He replied: "I bet you are, but it's not good enough," and he shot her too.'

Pastor Scroggins, who described his daughter as 'bubbly, energetic, extremely hard-working and conscientious,' said the shooter then ordered the remaining students to move into the center of the room and get down. When they didn't move quickly enough he yelled at them to move faster.

Lacey, the sixth of seven Scroggins children, found herself next to Treven Anspach who she knew from Sutherlin High School where she had spent three years before moving to Roseburg High for her senior year.

'She didn't know him well, but she recognized him,' her father said.

'She heard a loud pop, right next to her, it was so loud that her ears were ringing and she couldn't hear. That was the bullet that killed Anspach.

'Lacey told me: "Daddy, I was so scared." Anspach slumped to the ground, but moved closer to her to cover her.

'She felt the weight of his body on her. She opened her eyes and he was lying in the same direction as her, a little bit ahead of her. Then she saw his blood coming under her arms.

'She heard a gurgling sound coming from his throat and felt him move closer to her to cover her.'

On Thursday, Lacey (pictured with her father), who has dreams of becoming a surgeon, was on her fourth day at Umpqua Community College, taking a class taught by slain professor Larry Levine

Pastor Scroggins said he has reached out to the Anspach family (Treven Anspach pictured above) but at the time of the interview he had not connected

Lacey thought her lifesaver had died at that moment, but she learned it wasn't until later that Anspach passed away.

The horror in Snyder Hall only ended when police stormed the room. Lacey does not know whether police killed Harper-Mercer or whether he turned one of his guns on himself.

It was later revealed that the gunman took his own life after exchanging fire with police.

Lacey's medical training immediately went into effect.

'She got up and the first thing my daughter does is take off her scarf and use it as a tourniquet to staunch one woman's bleeding,' she then used her coat on a second gunshot victim, her father revealed.

Then police led her out of the room with the rest of the survivors, and that is when she finally broke down.

'I am so grateful to the officers who came in and finished it,' said Pastor Scroggins, who had received a phone call and driven to the college. 'I live about 20 minutes away, but the way I was driving, it only took me 10 or 15,' he said.

Now, two days after the horrific attack, Lacey is facing a hard road, even though she was not physically injured.

'One moment she is excellent, the next she is crying,' said her father.

'She is going through some survivor guilt, wondering why she lived while others died. We have spoken at great length, and she has no doubt that if it wasn't for Treven deliberately making sure she was covered in blood she would not be here today.'

Pastor Scroggins said he has reached out to the Anspach family but at the time of the interview he had not connected.
