An American man was exonerated Wednesday for a decades-old murder he did not commit, using evidence based on DNA and a genetic family tree, the first such result using a revolutionary investigative technique.
Christopher Tapp, 43, had served 20 of his 30-year sentence for the 1996 rape and murder of Angie Dodge.
On Wednesday, a court in the state of Idaho completely overturned his conviction based on evidence found with “genetic genealogy” — the technique used to identify the suspected “Golden State Killer” by making DNA matches with his distant relatives.
“It’s a new life, a new beginning, a new world for me, and I’m just gonna enjoy every day,” Tapp said at the end of the hearing, local media reported.
Tapp’s exoneration came after police arrested another suspect, Brian Dripps, in May. Dripps, who was identified using genetic genealogy, confessed to the crime.
Genetic genealogy first made headlines in April 2018, after it was used to find the alleged “Golden State Killer” in California who is blamed for 12 murders and more than 50 rapes dating back to the mid-1970s.
In that case — as well as about 70 others that have been solved since — DNA found at crime scenes was compared to the databases for genealogy websites.
The websites — widely advertised in the United States — allow users to post DNA test results and then generate a list of people with similar genomes, enabling users to find distant relatives.
The databases also allow police officers to search through people with similar genetic profiles to DNA found at crime scenes. Tracing back through family trees and seeing where the DNA crosses can lead investigators to a suspect.
But Tapp’s case is the first in which genetic genealogy has been used to prove innocence.
“It’s just such an incredible feeling to be a part of clearing an innocent man’s name,” CeCe Moore, the genetic genealogist who worked on the case, said in an interview with ABC.
The case against Tapp began to crumble before investigators started to use genetic genealogy.
In 1998, Tapp was sentenced to 30 years in prison based solely on his confession, which he then retracted.
In 2017, he was freed from prison in a court agreement, but the murder charge was not dropped.
A year later, his defense team obtained the right to test sperm traces found in Angie Dodge’s bedroom. Genetic genealogy led investigators to Brian Dripps.
Dripps, who in 1996 lived just across the street from Dodge, confessed to the crime after officers tested a cigarette butt he had thrown away against the crime scene DNA.
The Idaho Bonneville County prosecutor withdrew the charges against Tapp and filed a motion to exonerate him, which a judge endorsed on Wednesday.
Trump aides desperately try to downplay ‘order’ to US companies to leave China
Donald Trump's top aides on Sunday downplayed the idea of US companies being forced to abandon China any time soon, as an edict from the president ordering businesses to start looking for alternatives has been met with skepticism.
Treasury Secretary Steven Mnuchin and White House economics advisor Larry Kudlow took to the airwaves from France, where Trump is participating in the G7 summit, to smooth out tensions in the business community prompted by Trump's Friday tweet.
Trump said he has "no plan now" to bring US companies in line, and his aides quickly reinforced the message.
Trump sparks confusion at G7 before doubling down on China tariffs
President Donald Trump doubled down Sunday on his hard line against China after sowing confusion with statements that he might be willing to soften a trade war G7 partners fear threatens the world economy.
At the G7 summit in Biarritz, France, Trump announced a major trade deal with Japan and promised more of the same with Britain, once Brexit is done.
But the positives were overshadowed by a mix-up over his apparent expression of regret for the latest escalation in the US-China dispute.
"I have second thoughts about everything," he conceded to reporters when asked if he regretted his decision on Friday to ramp up tariffs on all Chinese imports, worth some $550 billion, in retaliation for Beijing's earlier hike of levies on US goods.
Persecuted Christians eye long-sought freedom in Sudan
Sudan's Christians suffered decades of persecution under the regime of Islamist general Omar al-Bashir. Now they hope his downfall will give the religious freedom they have long prayed for.
Deep within the maze of dusty alleys that honeycomb Omdurman, Khartoum's sprawling twin city, Yousef Zamgila's church is not visible from the street.
It is hidden in the courtyard of a friend's home and consists of a few iron benches, a pulpit and crosses hastily painted on pillars holding a corrugated roof.
"The previous centre got destroyed because we didn't have the right papers. They always refused... So we use the land of our neighbours," says the Lutheran reverend.
