A Concord man awaiting trial from jail for attempted murder is now accused of trying to persuade one of his two co-defendants and the victim to lie to authorities about who fired the gun.

Devon Gilligan, 18, was recently indicted on two felony counts of tampering with witnesses and informants between March and September. Since his arrest in mid-March, Gilligan has been incarcerated at the Merrimack County jail in Boscawen on charges of attempted murder, armed robbery, conspiracy to commit armed robbery and first-degree assault.

Merrimack County prosecutors allege that Gilligan asked another inmate to deliver letters to co-defendant Chea Chebo and the victim, Devyn Bowe Iriana, asking them to tell police that the shooter was “Nick.”

Nicholaus Castillo was with Chebo and Gilligan on the night of Nov. 24, 2018, outside the Penacook Place Apartments where Iriana was shot. Castillo, 19, previously of Hooksett, was recently sentenced as part of a plea agreement on a charge of conspiracy to commit armed robbery for his role in the incident and is serving a one-year jail sentence. Police say Gilligan and not Castillo was the ringleader.

According to a sworn police affidavit, Gilligan communicated over social media about plans to sell four grams of marijuana for $20 outside the apartment complex but had no intention of following through on the deal. Instead, they say he planned to rob Iriana, who he knew only on Snapchat, with the help of two friends – Castillo and Chebo.

Iriana later told police that when he drove around the back of the apartment complex, he saw three men approach his vehicle, including two of whom appeared from the tree line. After Gilligan got in the passenger seat, Iriana sped off, believing he was the target of a robbery.

Inside the car, Gilligan displayed a handgun and demanded that Iriana empty his pockets, the affidavit says. Iriana refused and told Gilligan to get out of the car, and that is when Gilligan stepped outside and quickly fired off several rounds, causing the car’s back windshield to shatter, police allege.

Iriana suffered a gunshot wound to his left shoulder and a graze mark on his right arm. Police said they found bullet holes in the car headrest directly behind where he was seated.

Through interviews, police learned that Chebo and Castillo had planned to get in the backseat of the sedan, but that Iriana had driven away before they were able to do so.

Gilligan was scheduled to stand trial on the attempted murder and robbery charges this month in Merrimack County Superior Court in Concord. However, the case has since been taken off the November trial docket. Assistant County Attorney Joe Cherniske said attorneys will meet on Dec. 6 for a dispositional conference and to select a new trial date.

In addition to the charges stemming from the botched robbery in Penacook, Gilligan is also accused of possessing marijuana while incarcerated at the county jail. He was indicted this fall on felony charges of delivery of articles prohibited and attempted falsification of physical evidence. Prosecutors allege Gilligan obtained the drug in July and then attempted to discard a cigarette in a toilet to avoid punishment.

The robbery case against Chebo is also still pending.
