2 suspects charged in fatal shooting of Cardinal Ritter College Prep grad

Prosecutors charged 17-year-old Jalin Jefferson and 18-year-old Corey Hardy with eight counts each in the death of Isis Mahr.

ST. LOUIS — Two suspects have been charged in connection to the death of a 19-year-old Cardinal Ritter College Prep grad

The St. Louis Circuit Attorney's Office issued charges Friday morning against 17-year-old Jalin Jefferson and 18-year-old Corey Hardy. Each suspect was charged with first-degree murder, three counts of assault and four counts of armed criminal action.

Isis Mahr was dropping off younger coworkers when a shooter opened fire on Oct. 17. Police said it happened around 1:15 a.m. near Goodfellow Boulevard and Switzer Avenue. 

Mahr was one of four people shot. She died at the scene. Police did not provide an update on the other three victims, who ranged in age from 16 to 18 years old.

Atif Mahr said his daughter Isis was working her way through nursing school so her parents wouldn’t have to pay a penny.

"I don't know what transpired other than it wasn't meant for her,” Mahr told 5 On Your Side last month. “Our young women need to watch the company they keep."

He said his daughter had a huge heart.

"If she loved you, she loved you hard,” the heartbroken father said. “If she loved you hard, she would give and do whatever she could."

Isis Mahr was fatally shot in St. Louis in October while dropping off younger coworkers.

A $1,000 reward was offered for any information that led to finding Isis' killer.

"Whoever did this, they have to live with it,” Mahr said. “The same way I have to live with it. We will let God deal with it."

The 2020 Cardinal Ritter College Prep graduate loved sports, especially soccer. Her father said after finishing up her soccer career, she helped out as an assistant coach.

Cardinal Ritter posted this statement on social media: 

"Cardinal Ritter College Prep is extremely devastated by the tragic loss of Class of 2020 graduate, Isis Mahr. Isis was loved by the entire Cardinal Ritter community and her bright light was taken far too soon. She was actively involved with her Cardinal Ritter family, recently volunteering with the athletic department and mentoring students. Our prayers and deepest sympathy go out to all family and friends of Isis as they cope with her sudden loss. Her death was an act of senseless violence in our community that must stop. To help Cardinal Ritter scholars through this devastation, counselors are available on campus. We will also be hosting a previously planned learning session with James Clark of the Urban League to speak with our scholars on how they can help lead St. Louis through this violence. Please join us in prayer and support for all those close to Isis."
