OMAHA, Neb. -- An Oklahoma man was sentenced to 12 1/2 years in prison following his conviction of several charges in Omaha.

Acting U.S. Attorney Susan Lehr said 50-year-old Johnny Dolph, originally of Oklahoma, was sentenced in Omaha on Thursday. He was sentenced for 10 counts: felon in possession of a firearm; possession of a firearm following a misdemeanor crime of domestic violence; two counts of false statement during the purchase of a firearm; conspiracy to tamper with documents or proceedings; tampering with documents or proceedings; two counts of conspiracy to assault a witness; and two counts for attempted assault of a witness. Dolph will serve a total of 150 months in prison with for a five-year term of supervised release after. There is no parole in the federal system.

According to court documents, Dolph is a self-professed “shot caller” for the Irish Mob Gang, which is a gang from the Oklahoma state prison system. Dolph came to Omaha in early 2021 on an interstate parole compact after a prison sentence in Kansas. Dolph had lied to Kansas and Nebraska’s parole offices, stating he would be living with someone in Omaha, who he claimed was his brother; the man was not his brother and is an affiliate of the Irish Mob Gang.

Officials said Dolph brought someone from Kansas to Omaha to set up a forgery operation in summer 2021. The person from Kansas was stopped by the Richardson County Sheriff’s Office in September 2021 and had several forgery related items that included counterfeit currency, forged Treasury checks, and document making implements.

Authorities said Dolph and co-defendant Norwood started talking to the other person from Kansas’s wife, identified as Victim 1 who was located in Omaha, in attempts to stop her from going to law enforcement. Victim 1 reported getting threatening communications from Dolph and Norwood. Dolph, Norwood, and others started researching and trying to find Victim 1.

According to court documents, Norwood started a straw-purchase for Dolph of a Hi-Point C9 9mm handgun from a website in fall 2021. The transfer was done on Oct. 25, 2021. Dolph was not allowed to have a firearm due to 11 felony convictions in Oklahoma and Kansas as well as two misdemeanor crimes of domestic violence in Kansas.

Officials said Dolph’s apartment in Omaha was searched in October 2021. The affiant for the search warrant was a federal agent with the Omaha Metro Financial Crimes Task Force, identified as Victim 2. Dolph started researching Victim 2 and found, what Dolph believed to be, Victim 2’s address; this address belonged to another person with the same name as Victim 2. Dolph drove by the address he found and filmed it. Dolph then sent this video and address to third parties and, in one such conversation, expressed a need to get a “throw away” gun.

Authorities said Dolph contacted Kate Ruth and requested that she come to Omaha from Kansas to help him find and carry out the “green light” he had put on Victim 1 in November 2021. Ruth was driven to Omaha by Juanita Gibson. Dolph paid for Ruth and Gibson’s gas and gave directions on where to go when they got to Omaha. Dolph and Norwood let Gibson and Ruth stay with them in their apartment. The four tired to find Victim 1. Ruth and Gibson drove to a home in Omaha at which Victim 1 was believed to be staying.

Documents state that law enforcement tried to arrest Dolph on a state warrant on March 1, 2022. Dolph was found and the Hi-Point C9 9mm handgun that Norwood had illegally bought for him was retrieved.  Dolph admitted to being a “shot caller” for the Irish Mob Gang and that he had researched and threatened Victim 1. Dolph stated that he wanted to stop Victim 1 from working with law enforcement. Dolph stated that he believed a “green light” to be an assault.

Officials said Dolph admitted to bringing “clovers,” female members of the Irish Mob Gang, from Kansas to Omaha to carry out the green light on Victim 1. He identified those clovers as Gibson and Ruth. Dolph also admitted that Norwood bought the Hi-Point C9 pistol for him. Dolph admitted to having the handgun and making a fake handgun purchase permit to make it seem like he had legally bought the firearm. Dolph admitted that he knew he was a felon and his social media had a photograph of him with the firearm, telling another person that Norwood had bought the it for him.

Authorities said Dolph was federally indicted for the firearms charges and was incarcerated at the Douglas County Correctional Center. Dolph called Norwood on March 30, 2022. In the calls, Norwood told Dolph that she was going to their trailer, which was at a storage facility in Omaha. Dolph then gave step-by-step instructions to Norwood on how to get an item that was hidden in an air compressor in the trailer. Dolph told Norwood to burn the item using gasoline and a blow torch. Dolph said the item would send him to prison. Dolph asked Norwood to take a picture of the item burning to prove to him that she destroyed it. An image of the item burning was found on Norwood’s phone.

According to court documents, the person from Kansas was sentenced on May 23, 2022, to time-served after serving a nine-month sentence for possession of counterfeit currency and possession of a document making implement or authentication feature and is currently serving a five-year term of supervised release. On July 18, 2023, Gibson pleaded guilty to conspiracy to assault a witness and attempted assault of a witness and her sentencing is scheduled for Oct. 13, 2023. Norwood and Ruth are currently pending trial and are presumed innocent unless and until they are proven guilty.

This case was investigated by the Federal Bureau of Investigation, the United States Secret Service, the Omaha Police Department, and the Richardson County Sheriff’s Office with assistance from the Kansas Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.
