Christy Mirack: 5 Fast Facts You Need to Know | Heavy.com
Christy Mirack was a 25-year-old 6th grade teacher at a Pennsylvania elementary school when, on December 21, 1992, her last day on earth, she gathered some Christmas presents in her arms for her students, put on her coat and gloves, and headed for the door.
She never made it outside.
A killer attacked, strangling and brutally beating the young teacher, whose homicide remained unsolved until June 2018 when authorities announced, at long last, a suspect in the case.
He is Raymond Rowe, a 49-year-old popular wedding and event DJ known professionally around Lancaster, Pennsylvania as "DJ Freez," authorities said in a news conference, and he's accused of criminal homicide in Mirack's death as a result of family DNA matching technology similar to that used in the Golden State Killer case in California.
In family DNA, authorities first link a DNA profile to a relative of the suspect – sometimes even a distant relative – and then backtrack through family trees until they narrow it down to one possible perpetrator.
Here's what you need to know:.
Christy Mirack Was Ambushed Inside Her Own Home.
The death of Christy Mirack, who was a 25-year-old 6th grade teacher at a local elementary school, was brutal and horrifying.
District Attorney Craig Stedman, of Lancaster County, Pennsylvania, detailed the crime scene in the news conference on June 25, 2018.
Mirack was living with a roommate at the time of her murder and, on December 21, 1992, the roommate left first to go to work.
Investigators believe that Christy Mirack was getting ready for work when the killer struck.
She was holding Christmas packages and had her jacket and gloves on, said the DA.
However, when she didn't appear at school that morning, her principal became concerned and went to the home to check on her.
It was 9:15 a.m., and he found the door ajar, and then "he went in and saw a shocking scene," said Stedman.
Mirack was lying unresponsive on the floor of the livingroom.
"It became obvious looking at the scene that a struggle had taken place," the DA says, noting that there were scuffed marks on the floow and the Christmas packages were "strewn about.
It's believed the killer sexually assaulted Mirack.
Her underwear, pants, and shoes were removed, and the clothing on her torso was pushed up.
A wooden cutting board was found near her head.
There was blood, and her face was distorted.
Mirack "had suffered a brutal beating as well," Stedman said in the news conference.
"She had her jacket on, her gloves on.
She was assaulted almost instantly at the doorway.".
It appeared that she had fought for her life, but she suffered blunt trauma to her neck, back, upper chest, and her jaw was fractured.
The cause of death was strangulation.
Horrifically, the coroner was able to find DNA from sperm on multiple areas of her body and in a section of the carpet directly under where her body was found.
Authorities developed a DNA profile of the suspect, and they put it in the database for offenders.
There was not a match, and the years passed by.
Eventually, authorities had run out of leads, when they heard about a new approach to crime solving involving genetic DNA testing on samples voluntarily submitted by people around the country, sometimes called "family DNA.".
Authorities had previously developed a drawing of the suspect via DNA profiling.
Authorities Say They Used Chewing Gum & Water Bottle to Solve the Case.
Authorities had the DNA of the killer, but no match.
However, then, in 2016, while at a seminar, they became aware of a company called Parabon NanoLabs, Stedman said.
They submitted a DNA profile from the carpet.
"We didn't have any more leads.
We didn't have any suspects," said Stedman in the news conference.
"Parabon was the last shot, and turnout out to be our best.
We didn't feel like we had any more arrows in the quiver.".
The DA pointed out that, although the process has been used in other cases throughout the country, it had not been used to solve a homicide in Pennsylvania yet.
Authorities contracted with Parabon.
Parabon's CEO Dr.
Steven Armentrout was also at the press conference on the Mirack case arrest.
"Together we worked efficiently and effectively," he said.
"It's a model I hope we can use across the country.".
He pointed out that critics have raised concerns about the process, especially since the higher-profile Golden State Killer arrest, but he believes those concerns are based on misconceptions.
He said that Parabon used a database called GEDmatch that is publicly available.
"People proactively upload their DNA files to this," he said of the site, which many people use to research their own ancestry and find relatives.
"The site is specifically designed to find genetic relatives." GEDmatch's database was also instrumental in the Golden State Killer case.
Armentrout said he had uploaded his own DNA to the site, and that he would be fine with it if law enforcement used his profile to "implicate even my closest relatives if their DNA is found at a crime scene.
Authorities uploaded the Mirack suspect DNA to the site, and set the file to private.
They say that GEDmatch shows the amount of shared DNA between two people and allowed Parabon to find distant cousins of the suspect, build family trees, and then suggest a suspect's name to law enforcement.
The lab often works with second and third cousin matches, said CeCe Moore, who works for Parabon.
Authorities have not said which relative's DNA matched Rowe's.
"We provide a highly scientific tip" to law enforcement, said Moore.
She said that the lab "analyzed family trees of those who share DNA with him.
We triangulated between these family trees and used genetic information to identify a possible suspect.
This is not magic. It is science.".
The district attorney said that Rowe had lived only a few miles from where the victim lived at that time.
"We had no connection to the defendant from our files," he said.
It didn't stop there.
Authorities don't make an arrest based on Parabon's findings.
It's just a tip.
They staked out Raymond Rowe, who was known as DJ Freez, and who was performing at an elementary school function.
On May 31, 2018, authorities observed him with a water bottle and chewing gum and obtained them when he abandoned the items, the DA said, adding that the DNA from those items matched the semen sample on the carpet and Mirack's body, in some cases by odds of 1 in 200 octillion (that's a thousand trillion trillions, a number with 27 zeroes behind it, according to the district attorney.
"This killer was at liberty from this brutal crime for longer than Christine Mirack was on this earth alive and they steered us in the path of holding him finally accountable," said the DA.
Rowe, the Suspect, Got His Start as a DJ by Working as a Break Dancer & Winning Local DJ Battles.
Raymond Rowe owns a company called Freez Entertainment, LLC, where he is known as DJ Freez.
The website labels the company as "an AWARD WINNING DJ Company that provides music entertainment for any occassion (sic).
