Aug. 4—An inmate who was mistakenly released by the Santa Fe County jail Tuesday night after using another man's identity was recaptured about 24 hours later at the Presbyterian Santa Fe Medical Center on Beckner Road, authorities said.

Santa Fe County Sheriff Adan Mendoza said a vigilant staff member at the hospital recognized 35-year-old Jarrod Bearden and promptly alerted law enforcement.

Bearden was arrested around 7:30 p.m. Wednesday in a treatment room, Mendoza said, and was taken into custody without incident.

He was returned to the county jail, the sheriff's office reported in its online daily incident log.

Mendoza said Bearden was trying to receive medical treatment at the hospital but declined to elaborate on his medical condition.

Officials said Bearden had tricked jail officials into letting him walk free Tuesday by misrepresenting his identity — which will net him additional charges, Mendoza said.

It was unclear how he was able to convince jail staff his identity matched that of another inmate.

This is a developing story. Check back for more details.

Killexams : Above-normal hurricane season still expected despite slow start, forecasters say

Right on the cusp of peak hurricane season, the National Oceanic and Atmospheric Administration announced Thursday it’s continuing to forecast an active season.

During a mid-season update, the government agency announced the likelihood of an above-normal Atlantic hurricane season now stands at 60%. The prediction falls slightly from the agency’s May prediction, when it forecast a 65% chance of an above-normal season.

To date, there have been three named storms this year. While it may have felt like June and July were slower than usual, the quieter months were not unexpected, according to Matthew Rosencrans, the lead hurricane season outlook forecaster at the agency. August to October is when 90% of hurricane activity occurs, he said.

The 5% decrease in the chance of an above-normal hurricane season translated to a 5% increase in a near-normal season, from 25% in May to 30% Thursday, the agency said. The chances of a below-normal season remain at 10%.

The agency said sea surface temperatures in the Atlantic have been more varied than expected. Some parts are warmer than normal while in other areas, such as off the coast of Portugal, there are temperatures that are slightly cooler, Rosencrans said.

In all, the weather agency is predicting 14 to 20 named storms. Six to 10 of those could become hurricanes, and three to five of those could be major hurricanes. Major hurricanes are categorized as a Category 3 or above and have winds of at least 110 mph.

“While the tropics have been relatively quiet over the last month, remember that it only takes one landfall storm to devastate a community,” Rosencrans said. “Now is the time to know your risk, develop a plan and be prepared for potential tropical storms or hurricanes.”

Rosencrans said that last year there wasn’t much tropical development from July through Aug. 11. After that, an average of 2.4 tropical storms formed each week until the end of September.

By the end of that hurricane season, 2021 was the third-busiest year on record for named storms, Rosencrans said, and 2020 was the busiest year on record — those two years produced a combined 51 named storms.

Rosencrans said the government agency’s predictions are based on long-term data, not just information from the past few years.

So far, this season may seem behind when comparing formed storms to accurate years, but really, it’s closer to a normal hurricane season, he said.

La Niña conditions likely will remain in place for the rest of 2022, which could enhance the chances of more hurricane activity, the agency said. Weaker tropical Atlantic trade winds and periodically above-normal Atlantic sea surface temperatures also could lead to a more active season.
