ST. LOUIS COUNTY, Mo. – Police have arrested a man accused of shooting his girlfriend to death Saturday morning in north St. Louis County.

Darrick Dillon, 47, faces felony charges in the shooting death of Adayshia Jackson, 28. Police say Jackson was in a relationship with Dillon and shot to death after the two ended up in an argument.

Police found Jackson deceased around 2 a.m. Saturday at a home in the 1100 block of Soria Street while responding to a welfare check. Jackson suffered multiple gunshot wounds, and evidence from the scene was linked to Dillon.

According to court documents, Jackson reportedly ran out of the house after being shot, but didn’t make it far. Dillon is accused of dragging Jackson’s body back into the home, stealing her cell phone and disposing of the gun connected with her death. Dillon confessed to his parents he made a mistake and “was going away,” per court documents.

Dillon is jailed in St. Louis County on a $500,000 cash-only bond. Prosecutors have charged him with second-degree murder, armed criminal action and three counts of tampering with physical evidence in a felony prosecution.

The St. Louis County Police Department is handling the investigation into Jackson’s death.
