TUCSON Arizona The family of Nancy Guthrie has increased the reward for information leading to her recovery or the arrest of those responsible to one million dollars as the search for the 84 year old enters its twenty fourth day.

Guthrie was taken from her home in the dark of night on February 1 in what authorities are investigating as a suspected abduction. Surveillance footage released by investigators shows a masked individual near her front door the night she disappeared.

Initially the reward was set at just 2500 dollars by the Pima County Sheriff. As the case drew national attention and concern for her safety intensified the amount grew substantially. The Federal Bureau of Investigation is also offering a 100000 dollar reward.

In an emotional plea her daughter Savannah Guthrie described the unbearable pain the family has endured.

“It is Day 24 since our mom was taken in the dark of night from her bed, and every hour and minute and second and every long night has been agony since then of worrying about her and fearing for her and aching for her and most of all just missing her,” Guthrie said.

She added, “Someone out there knows something that can bring her home. Somebody knows, and we are begging you to please come forward now.”

Investigators say they have received thousands of tips but no major breakthrough has been announced. Authorities remain deeply concerned for Nancy Guthrie’s health, noting that she requires daily medication.

The FBI encouraged anyone with information to contact the tip line at 1 800 CALL FBI or 1 800 225 5324 as the search continues.

Law enforcement officials say the investigation remains active and they are pursuing every possible lead as the family waits for answers and holds onto hope.
