The last of four young men involved in the brutal rape of two teens on Harriet Island during the summer of 2017 received 32 years in prison for his role in the attack.

Ramsey County District Judge Timothy Mulrooney on Friday sentenced Choncey Stewart, 18, on two counts of aiding and abetting first-degree criminal sexual conduct, two counts of kidnapping and four counts of first-degree aggravated robbery.

The sentence was lower than the roughly 50 years prosecutors sought.

Authorities say Stewart, who was 16 at the time, was the instigator and gunman during the incident, which took place around 11 p.m. June 5.

He and three others — Devontre Jordan Vann, 20, Deandray Artez Easley, 20, Vershone Jaquay Hodges, 21 — encountered a group of four teens — two girls and their two male friends — on Harriet Island that night.

After exchanging some words — Stewart knew one of them — the group forced the boys to strip to their underwear and lie in the grass as three of the young men, including Stewart, took turns raping the girls.

All the while Stewart had the gun, and often used it to threaten the victims.

Three of the four victims were minors. One of the girls was 18 at the time.

Previously, the longest sentence in the case went to Easley, the only one of the four to take his case to trial. Easley was sentenced to 30 years in prison. Hodges and Vann received 25 and 23 years, respectively, after reaching plea deals.

Stewart’s sentence came about two months after he pleaded guilty to the charges.

He and his friends had gone to the park that night to shoot a music video, according to court testimony from the others’ cases. They were high on Xanax and drunk on tequila at the time of the assaults.

Both of the female victims spoke at a previous sentencing hearing, where they described through tears how they struggle with ongoing panic attacks, severe depression, sleeplessness and hopelessness since the assault.
