ST. LOUIS,Mo. (KMOV.com) - Nearly six months after the grandson of the owner of “Sweetie Pie’s” restaurants was shot to death, Andre Montgomery’s loved ones are still demanding justice.

Someone killed the 2013 graduate of McCluer North High School the night of Monday, March 14. Since Montgomery's killer is still on the loose, his family and friends are holding a candlelight memorial service called "JUSTICE FOR DRE" hoping someone will come forward with information pertaining to the case so the St. Louis Police Department can catch Montgomery's killer. The memorial service will be held Monday, September 12 from 6 p.m. to 8 p.m. on the patio of Sweetie Pie’s Upper Crust located at 3643 Delmar Boulevard near the Fox Theatre.

The 21-year-old shooting victim’s grandmother, Robbie Montgomery, is the star of the reality show “Welcome to Sweetie Pie’s” on the Oprah Winfrey Network. Miss Robbie was also a former backup singer to Ike and Tina Turner.

When asked about the status of the investigation into her grandson's cold-blooded killing, Miss Robbie said, "Someone called my grandson on his cell phone when he was in the recording studio. He went outside, then someone shot him five times. They got his phone! Can't they trace his phone?"

The location of the recording studio was in a North St. Louis home in the 3900 block of Natural Bridge.

In a statement, St. Louis Police Spokeswoman Leah Freeman wrote: “There is no new information in the homicide of Andre Montgomery. The investigation is ongoing and anyone with information is asked to call CrimeStoppers."

The CrimeStoppers telephone hotline is 1-866-371-TIPS (8477). Tips on homicide cases that lead to arrests could yield rewards ranging between $2,000 to $5,000.
