The Brunswick News reports that Karimah Elkins and her 19-year-old daughter, Sabrina Elkins, entered written pleas Friday. Both are charged with evidence tampering in the case against 18-year-old De'Marquise Elkins. He faces a malice murder charge and other counts in the March 21 slaying of 13-month-old Antonio Santiago in coastal Brunswick.

An indictment accuses the two Elkins women of disposing of a .22-caliber pistol in a small saltwater pond where it was later found by police. The gun is being tested to determine whether it matches the weapon that killed the child.
