A 21-year-old Oklahoma woman has agreed to plead guilty in last year’s robbery of two Florida college students that ended in the shooting death of one victim in the Talladega National Forest.

Yasmine Marie Adel Hider’s plea agreement was made public in federal court in Birmingham Monday. She pleaded guilty to second-degree murder, kidnapping of a victim not resulting in death, and robbery.

She is one of two women charged federally in the slaying of 22-year-old Adam Simjee. He and his girlfriend, Mikayla Paulus, were robbed at gunpoint while they were hiking in Cheaha State Park on Sunday, Aug. 14, 2022.

Krystal Diane Pinkins, 37, is also under federal indictment on the same charges. Both women also are charged with unlawful use of a firearm during a crime of violence.

Hider’s guilty plea included dismissal of the gun charge.

Pinkins’ trial is set for Sept. 25.

Hider and Pinkins, previously described as “living off the grid,” are also facing murder charges in Clay County. Trial dates have not been announced in the state cases.

A Clay County judge has issued a gag order in the state case that prevents anyone associated with the case – including lawyers and witnesses – from speaking with the media about the case.

Under the plea agreement, prosecutors will ask that Hider be sentenced to 35 years in federal prison, followed by supervised release.

Simjee, 22, was about to begin the finance program at the University of Central Florida, and Paulus, 20, was beginning work on her master’s degree in counseling, also at UCF.

Paulus previously spoke with AL.com about what happened that morning.

The couple arrived at Cheaha State Park in Clay County, taking in the waterfalls and Boulder Rock.

It was mid-morning when they were flagged down by two women who said they were having car trouble, and the couple stopped to help. That is the way they were raised, and what they had been taught to do.

“I called my dad (to ask for car repair advice), watched some YouTube videos and tried to fix car,’’ Paulus said. “When we realized it couldn’t be fixed, I asked if she needed anything else.”

“She (Hider) pulled a gun, said put your hands up, walk into the woods and drop your phone and keys,’’ Paulus recounted.

Simjee, she said, was a “proud supporter of the Second Amendment” and had tucked his gun in his waistband when they stopped to help the women.

“He had his gun in his waistband the whole time because he said it was suspicious and this is how people get robbed,’’ Paulus said.

“My whole body went numb, but I knew I would at least be OK,’’ she said. “I was terrified, but I knew at any point Adam was going to pull his gun out.”

“He always made sure that I knew that I was protected and taken care of,’’ she said.

Hider asked them for their banking information and cell phone passwords.

“When she (the suspect) dropped her guard for a second, and lowered her gun for a second, he pulled out his gun and told her to get on the ground,’’ Paulus said. “She started messing with her gun and it was jamming but they shot at each other.”

“She was shot three times and he was shot once. Her femur was shattered so she couldn’t get away,’’ she said.

The second female suspect – Pinkins – ran off into the woods once the gunfire erupted.

Paulus called 911 and remained on the phone with dispatchers for about 30 minutes. “I had to do chest compressions the last five minutes,’’ she said.

Simjee was unresponsive and never spoke again after he was shot.

“He went down, and he was struggling,’’ she Paulus said.

Sheriff Jim Studdard has said while authorities were searching for the second suspect – Pinkins – they were led to a large group of tents that had been sent up in the forest. He described it as a base camp, which was located about a half mile from the crime scene.

As authorities were approaching the base camp, they observed Pinkins standing near the tents. As officers were ordering Pinkins to the ground, a 5-year-old child ran from the woods holding a loaded shotgun.

Law enforcement officers told the child to put down the weapon however the child continued to his mother’s location before putting the gun on the ground.

Pinkins is also charged with endangering the welfare of a child, and the child is now in the custody of DHR.

According to court records, when investigators interviewed Pinkins following her arrest, she said the gun used to kill Simjee was hers. The two had discussed using the gun to carjack someone to go get food.

Pinkins stated she and Hider flagged down an older woman the day before the murder, asking the woman to drive them to the location of their vehicle, which had been broken down for several weeks.

Hider told investigators she was waiting on the side of the road to stop so they could take a car to go get food. She said Pinkins was with her when she got shot.

“Hider asked agents, ‘Did he die?’ and stated, ‘I didn’t want to hurt anybody,’’’ documents show. “I took his whole life away; now he can’t tell his story.’’’
