A Pennsylvania woman who had been missing for more than a decade has pleaded not guilty to charges in Nassau County, Florida, as she remains a suspect in the disappearance of another woman last month.

Jennifer Sybert, whose real name is Kimberly Kessler, had her attorney enter a written plea of not guilty to a charge of grand theft auto on Wednesday after authorities said she was seen on surveillance footage dropping off 34-year-old Joleen Cummings’ car hours after she was last seen.

Sybert, aka Kessler, worked with Cummings at a hair salon in Yulee, Florida, and is believed to be the last person to see Cummings before she disappeared nearly a month ago, authorities said.

Cummings’ mother, Ann Johnson, reported her missing on May 14 after she failed to pick up her kids on Mother’s Day.

Kessler has been charged in Nassau County under the name Sybert and has not yet been charged in connection with Cummings’ disappearance.

The Nassau County Sheriff’s Office said it's still working to gather more evidence. Sheriff Bill Leeper said last month investigators have reason to believe that Cummings is no longer alive.

Sheriffs in St. Johns County, Florida, arrested Sybert on May 16, which was when authorities learned her real name was Kimberly Kessler -- the same Kimberly Kessler who had been reported missing from Butler County, Pennsylvania, in 2004. The Nassau County Sheriff’s Office said this month that since that time Kessler is believed to have used at least 18 different aliases and lived in more than a dozen states.

She's believed to have gotten her most recent alias, Jennifer Sybert, from the grave of a deceased teenager in Butler County, according to County District Attorney Richard Goldinger.

Sybert remains in jail on a $500,000 bond.

A federal judge in Arizona has denied a request for a new trial against former Maricopa County Sheriff Joe Arpaio, which was brought on by the son of Arizona Sen. Jeff Flake.

U.S. District Judge Neil Wake ruled that despite claims by Austin Flake’s attorney, Stephen Montoya, that newly uncovered evidence warranted a new trial, Wake ruled that the evidence was “irrelevant as to Arpaio.”

Montoya told ABC News he was “disappointed” with the decision.

The lawsuit stemmed from the deaths of 21 dogs at a Phoenix-area kennel owned by the parents of Austin Flake’s now ex-wife, Logan Brown. Austin Flake and Brown were temporarily watching the property in June 2014 when the dogs died in the sweltering Arizona heat.

The couple maintained that an air conditioner on the property failed overnight and the dogs died accidentally. But the Maricopa County Sheriff’s Office would subsequently investigate and recommend felony charges of animal cruelty against Austin Flake and Brown in September 2014.

The two were indicted in October, but the charges were dropped just two months later when the Maricopa County Attorney’s Office said the case presented to the grand jury did not take into account the possibility that the air conditioner had failed. The Maricopa County Attorney’s Office told ABC News they have no comment on the case.

The suspect being held in a Galveston County, Texas jail following last week's deadly shooting at Sante Fe High School is making a push to get out of jail on bond.

Attorneys for 17-year-old Dimitrios Pagourtzis filed a motion Wednesday requesting that a "reasonable bond" be set. His attorneys argue that Pagourtzis has a constitutional right to a reasonable bail, and they furthermore state that his family has the means to post that bail.

His attorneys did not specify in their motion what they consider a "reasonable bond" to be.

Pagourtzis has been held in Galveston County Jail without bond since he was arrested following the May 18 shooting that killed eight students and two teachers. Thirteen others were injured.

A judge has yet to rule on the motion.

Pagourtzis is facing multiple counts of capital murder as well as aggravated assault on a public servant.

An attorney representing one of the two cousins accused in the deaths of four young men in Pennsylvania last summer, is now off the case and admits that he leaked evidence to the media.
 
A day after a Bucks County judge granted a request by attorney Craig Penglase to no longer represent Sean Kratz, the Bucks County District Attorney’s Office has released a letter written by Penglase in which he admits to leaking so-called confession tapes of his client and Kratz’s cousin, Cosmo DiNardo, to the media.
 
The tapes were discussed during court appearances by DiNardo and Kratz last week, but the DA’s Office had refused to publicly release them. Prosecutors said they did not consider the tapes to be public record.
 
Later that evening, however, a local media outlet aired portions of the tapes in which DiNardo could be heard saying “I don’t know why I did this” and calmly admits to murdering Jimi Patrick, Mark Sturgis, and Tom Meo. Kratz could also be heard discussing the death of Dean Finocchiaro, saying “I pulled the gun out. You know, I, I aimed it in the air … Closed my eyes, and fired a shot.”
