A 22-year-old Casper woman pleaded guilty to two accessory charges in Natrona County District Court on Thursday for her role in a shooting incident that left one man dead and another wounded in May 2025.
Nevaeh Marie Neeman pleaded guilty to amended charges of accessory before the fact to aggravated assault and battery. She also pleaded guilty to accessory after the fact for driving a getaway car and helping get rid of weapons involved in the shooting.
Neeman helped her boyfriend and another man go to a south-side Casper apartment complex last May for what she thought was going to be a fight with a third man to retrieve a pistol.
Instead, her armed 21-year-old boyfriend, Jadin Triplett, and his 20-year-old accomplice, Anicio Bernard, got into a shootout that left Bernard dead and the intended target wounded.
Neeman previously was charged with conspiracy to commit aggravated assault and accessory before the fact to aggravated assault for her role in the shooting at Foxhill Apartments.
Neeman’s plea was part of a deal made with the Natrona County District Attorney’s Office.
Chief Deputy District Attorney Blaine Nelson outlined the deal at Neeman’s arraignment hearing, telling Judge Catherine Wilking the charges had been amended to reflect Neeman’s understanding that Triplett and Bernard were going to a Foxhill Apartments, where Triplett’s cousin was staying, to get a weapon back but not necessarily to shoot him.
A police affidavit states that when the pair accompanied by Neeman entered the apartment, both men were masked and Bernard had his weapon out with a round in the chamber.
Under the agreement made with Neeman and her attorney, Kristen Schlattmann, Neeman would have a four- to five-year sentence “imposed” for the accessory before the fact charge and two to three years for the accessory after the fact charge, Nelson said.
Both sentences would be served concurrently.
Youth Offender Recommendation
Nelson said he and Schlattman also are recommending Neeman be entered into the Wyoming Department of Corrections’ youthful offender program. Neeman also agreed to be a witness for the prosecution.
“Ms. Neeman would cooperate and testify truthfully … in the matter of any confederates in this case,” Nelson said.
Neeman would also need to provide any restitution in the case.
Wilking went over the charges and the plea agreement with Neeman and told her that as judge she would not accept it until after a pre-sentence investigation.
Wilking then asked Neeman if she understood the deal and the potential consequences.
“Yes, your honor,” Neeman said.
Neeman then pleaded guilty to both charges. She told the court that she drove the car to the apartment complex on May 11, 2025, and knew that Triplett and Bernard were armed.
Schlattman asked if she expected a physical confrontation.
“Yes, ma’am,” she said.
Schlattman asked if she should have anticipated firearms would be used.
“Yeah,” Neeman said.
On the second count involving being an accessory after the fact, Neeman told the court she drove “the car from the scene and (didn’t call) 911 when I should have.”
Nelson added that she knew that there was going to be violence because of a comment made that (the cousin) was going to get “f—up.” He said she also helped conceal the firearms after the shooting.
Wilking asked her if she agreed with Nelson’s statements.
“Yes, your honor,” Neeman said.
Affidavit Evidence
At Nelson's recommendation, the judge also said she would use information from Neeman’s statements in the police affidavit to provide a factual basis for her guilt.
In the affidavit, Neeman told Casper Police that Triplett’s cousin had been drinking at their apartment two weeks prior to the shooting and after he left Triplett noticed that his Glock 26 firearm was missing. Neeman said a few days before the shooting the cousin had “flashed” the gun to a mutual friend.
On the day of the shooting, Bernard had a deliberate FaceTime call with the cousin where he again flashed the gun and Bernard asked if he could come over and “hang out.” The cousin agreed, the affidavit states.
Neeman then told police Bernard had a bag with a pistol in it while at their apartment and at some point put the gun in his waistband. The affidavit states she drove Bernard, his girlfriend, and Triplett to the apartment complex.
Both Bernard and Triplett had ski masks.
When the pair got out of the car to approach the apartment building, they put down the ski masks. The affidavit states Neeman, who accompanied the pair into the apartment, told police Triplett had a pistol with “rifle ammunition” and she knew then that “something bad was going to happen.”
“Neeman admitted the plan was that Triplett and Bernard would beat (the cousin) up and get the gun back,” the affidavit states.
Instead, Neeman told police that Bernard chambered a round in his weapon and once inside the apartment yelled “give me all your sh-t, give me all your sh-t.” The cousin pulled out his weapon and he and Bernard exchanged fire.
The affidavit states Neeman told police Triplett also pulled his weapon but that it “seemed like his gun jammed."
Triplett told police he forgot to take off the safety and “stated that he took this as a sign and left the apartment,” the affidavit says.
The affidavit states that Neeman told police she saw Bernard collapse on the steps outside the apartment building and that he told them to “run.”
“Neeman believed she saw Bernard take his last breath,” the affidavit states.
Bond Request
In court Thursday, after Neeman’s plea, Schlattmann asked Wilking to consider lowering Neeman’s bond from $25,000 to $10,000 or $15,000.
Schlattman said Neeman has a 3-year-old son and only had video contact with him. Neeman has been attending AA meetings and getting counseling in the jail.
“She has been doing great work in the detention center,” Schlattman said.
She said Neeman wants to prepare her son for the separation that will come when she is sentenced.
“She’s ready to accept her consequences,” Schlattman said.
Nelson argued that the bond is appropriate for the seriousness of the case and charges against her.
Wilking agreed to lower the bond to $15,000 cash or surety.
Neeman’s co-defendant Triplett has pleaded not guilty to charges of aggravated assault and battery and conspiracy to commit aggravated assault and battery. His cases remain pending.
Triplett’s cousin who was shot by Bernard was initially hospitalized with critical injuries and later released.
