LOS ANGELES - Detectives searching for the kidnapped mother of a top US TV news anchor said Thursday blood discovered on her doorstep belonged to the missing 84-year-old woman, in the latest twist in a case that has gripped America.
Nancy Guthrie, mother of NBC News "Today" co-host Savannah Guthrie, is believed to have been kidnapped from her home in Tucson, Arizona, sometime on Saturday night or Sunday morning, sparking a massive hunt and a race against time to find her.
Pima County Sheriff Chris Nanos told a packed press conference that initial DNA tests on droplets of blood found at the entrance to Nancy Guthrie's house reveal it is hers.
But four days after her disappearance, he admitted detectives were no closer to finding who was responsible for the woman's abduction.
"Everybody's still a suspect in our eyes," Nanos said.
However he said authorities believed she was still alive.
"Right now, we believe Nancy is still out there," Nanos told reporters. "We want her home."
Her disappearance has garnered wall-to-wall coverage in US media, with dozens of reporters and camera crews descending on the quiet Arizona suburb where she lives.
Nancy Guthrie's son issued a fresh plea after the press conference Thursday, saying the family had no new information regarding her whereabouts.
"Whoever is out there holding our mother, we want to hear from you," Camron Guthrie said in a video posted on Instagram.
"We haven't heard anything directly. We need you to reach out and we need a way to communicate with you so we can move forward. But first we have to know that you have our mom."
