Officials say the parents of an infant who was found dead at their Mississippi home drove with their 2-year-old daughter to Georgia, where they are being held on felony drug warrants.

Police in Sylvester, about 170 miles south of Atlanta, say 2-year-old Maliah Harris was found unharmed at 12:09 a.m. Thursday in a traffic stop after an Amber Alert was issued. Police Chief Robert Jennings says 34-year-old Donald Boyd Harris and 31-year-old Allison Studdard are wanted on warrants for possession of methamphetamine in Mississippi. Jennings says drugs also were found in the car, with additional charges possible.

Maliah's 7-month-old sister, Alyssa, was found dead early Wednesday. County Coroner Greg Merchant says an autopsy didn't reveal a preliminary cause of death. A toxicology report is pending.

Sheriff Mike Arledge tells WCBI-TV (http://bit.ly/1mHQiQ9) methamphetamine was found at the scene.
