Montgomery County Department of Police(WASHINGTON) — The suspect behind a string of sexual assaults and one slaying that “terrorized” Washington, D.C., women in the 1990s is now in custody after he was nabbed through the novel investigative tool of genetic genealogy, authorities said.“Between 1991 and 1998 a man terrorized our community as he brutally preyed upon and attacked multiple women across this region,” D.C. Police Chief Peter Newsham said at a Thursday news conference.Known as the Potomac River Rapist, the suspect — now identified by police as 60-year-old Giles Daniel Warrick — allegedly committed at least eight sexual assaults in Montgomery County, Maryland, and two sexual assaults in Washington, D.C., authorities said.The Potomac River Rapist would cut phone lines, force his way into homes, cover the victims’ heads and sexually assault them, authorities said.It appears the attacks became more violent over time, police said. Among the 10 victims was Christine Mirzayan, a 29-year-old congressional fellow who was sexually assaulted, hit on the head, “brutally beaten” and murdered, Newsham said. The murder weapon was a 73-pound rock, according to the FBI.But the identity of the suspected Potomac River Rapist was unknown for decades, until genetic genealogy came into play, said Montgomery County Police Chief Marcus Jones.Genetic genealogy compares unknown DNA evidence from a crime scene to public genetic databases to identify suspects through their family members who voluntarily uploaded their DNA to those databases.Genetic genealogy has been called a “game-changer” in the effort to crack cold cases. Since the arrest of the suspected “Golden State Killer” in April 2018, about 100 suspects have been identified through the technology, according to CeCe Moore, the chief genealogist at Parabon NanoLabs. Moore, who has appeared as an expert in ABC News “20/20” episodes and has been quoted in ABCNews.com articles, investigated the Potomac River Rapist case among others.Police did not elaborate on which of Warrick’s relatives had voluntarily submitted their DNA to databases. Police also did not disclose how they obtained Warrick’s DNA to confirm the match.Warrick was arrested Wednesday at his home in Horry County, South Carolina, and has been charged with six counts of first-degree rape in Montgomery County, police said. All six of those cases were linked to the same suspect DNA, police said.Warrick is expected to be extradited to D.C. to be charged with first-degree murder and the D.C.-area sexual assaults, Newsham said.Warrick, who had a landscaping company and worked as a utility company contractor, had been living in the D.C. area before recently moving to South Carolina, Jones said.It was not immediately clear when Warrick will appear in court.“Detectives are concerned there may be additional victims in the area given the prolonged period of time that has elapsed involving Giles Daniel Warrick,” Montgomery County police said. “Anyone with additional information is asked to contact the Major Crimes Division at 240-773-5070.”Copyright © 2019, ABC Audio.

The president went on to reject negative characterizations of his proposal by immigration hard-liners in the media, including conservative commentator Ann Coulter, who tweeted Saturday: “Trump proposes amnesty. We voted for Trump and got Jeb!”Conservative commentator Ann Coulter | Rich Polk/Getty Images for Politicon“No, Amnesty is not a part of my offer,” Trump wrote Sunday, claiming that “Amnesty will be used only on a much bigger deal.”He added: “Likewise there will be no big push to remove the 11,000,000 plus people who are here illegally-but be careful Nancy!”The president continued to criticize the House speaker online, scolding Pelosi at 8:35 a.m. for behaving “so irrationally” during negotiations to reopen the government and accusing her of giving in to demands from more liberal lawmakers in her caucus.“She is so petrified of the ‘lefties’ in her party that she has lost control,” Trump tweeted. “And by the way, clean up the streets in San Francisco, they are disgusting!”Trump also told Pelosi via tweet that he was “still thinking about the State of the Union speech,” teasing that “there are so many options” to deliver the address she requested he postpone as long as the federal government is closed. Nineteen minutes later appeared a warning from the commander-in-chief concerning wintry conditions, along with some morning fodder for skeptics of climate change. The day’s weather included snow in the Midwest, and icy conditions across the northeast.“Be careful and try staying in your house,” tweeted the president, who remained in the White House throughout Sunday. “Large parts of the Country are suffering from tremendous amounts of snow and near record setting cold. Amazing how big this system is. Wouldn’t be bad to have a little of that good old fashioned Global Warming right now!”“We must now work together, after decades of abuse, to finally fix the Humanitarian, Criminal & Drug Crisis at our Border.” — Donald TrumpNext up came the main focus of the day: the reaction on Capitol Hill to Trump’s Saturday address from the White House, during which he laid out a potential compromise plan to end the government shutdown.The president pitched a bill to provide certain border security measures and temporary protection for some undocumented immigrants in exchange for $5.7 billion in border wall funding. Democratic leaders in Congress promptly declared the proposal dead-on-arrival, with House Speaker Nancy Pelosi dubbing Trump’s overture a “nonstarter.”“Nancy Pelosi and some of the Democrats turned down my offer yesterday before I even got up to speak,” Trump complained on Twitter Sunday, in what would be the first of four posts to take aim at the California Democrat. President Donald Trump rung in Day 30 of the longest government shutdown in U.S. history, as well as the two-year anniversary of his tenure in the Oval Office, with a mammoth 40 posts to his Twitter feed over the course of Sunday.The president’s day on his favored social media platform began as most do — with some boasting about the state of the American economy, accompanied by lamentations over its perceived lack of coverage by members of the news media. Through the dizzying day, he would cover a variety of topics with his tweets and assorted retweets, even landing in the world of sports late in the evening.“Always heard that as President, ‘it’s all about the economy!’ Well, we have one of the best economies in the history of our Country,” Trump wrote online at 7:40 a.m. “Big GDP, lowest unemployment, companies coming back to the U.S. in BIG numbers, great new trade deals happening, & more. But LITTLE media mention!” At 9:03 a.m., the president claimed that his “poll numbers with Hispanics” had increased to 50 percent, and asserted at 9:20 a.m. that despite the shutdown, the government is still “building and renovating big sections” of his proposed wall along the U.S.-Mexico border.“Building, after all, is what I do best, even when money is not readily available!” he explained.Pelosi and other Democrats talk to journalists following a meeting with U.S. President Donald Trump | Chip Somodevilla/Getty ImagesThe next post to appear on the president’s timeline was a message of thanks to the father of right-wing conspiracy theorist Jacob Wohl, followed by a jab at the media for “not giving us credit for the tremendous progress we have made with North Korea.” The White House announced Friday that Trump will hold a second summit with North Korean leader Kim Jong Un in late February.Trump at 1:16 p.m. posted a high-sheen, roughly one-and-a-half minute video pre-produced by the White House and meant to commemorate his two years in office, before launching into a series of retweets of prominent conservatives praising the president’s Saturday address on border security.In total, Trump reposted 14 messages of support from GOP lawmakers, as well as tweets by Vice President Mike Pence and conservative radio personality Mark Levin.At 7:48 p.m., the president thanked James Woods for a congratulatory tweet from the conservative actor, and two minutes later retweeted a message from his wife, Melania Trump, writing: “A truly great First Lady who doesn’t get the credit she deserves!” Actor James Woods popped into the president’s twitter feed in the evening | Slaven Vlasic/Getty ImagesAt 8:25 p.m., the president tweeted a message to the federal workers still furloughed as a result of the shutdown.“To all of the great people who are working so hard for your Country and not getting paid I say, THANK YOU – YOU ARE GREAT PATRIOTS!” Trump wrote online. “We must now work together, after decades of abuse, to finally fix the Humanitarian, Criminal & Drug Crisis at our Border. WE WILL WIN BIG!”After a break of more than two hours, he kicked back in to salute the NFL’s New England Patriots upon returning to the Super Bowl: “Congratulations to Bob Kraft, Bill Belichick, Tom Brady and the entire New England Patriots team on a great game and season. Will be a fantastic Super Bowl!“ After defeating the Kansas City Chiefs on Sunday night, they will face the Los Angeles Rams in two weeks.He followed that with a retweet of his son, Donald Jr., then one more where he made a pitch for the case of former baseball pitching ace Curt Schilling for baseball’s Hall of Fame. The results of that election are due Tuesday.
