One person has been arrested and charged in the disappearance of a 34-year-old Memphis teacher, although police said Sunday morning they still didn’t know where Eliza Fletcher is.

In an early morning tweet, Memphis Police said 38-year-old Cleotha Abston is charged with especially aggravated kidnapping and tampering with evidence. Police did not give more information on Abston or any prior connection to Fletcher.

The arrest came roughly 12 hours after police announced they had found the GMC Terrain they said was used in Fletcher’s abduction early Friday morning as she jogged on the University of Memphis campus.

The disappearance of Fletcher, a teacher at St. Mary’s Episcopal School in Memphis and mother of two, set off a large-scale search involving Memphis Police, the Tennessee Bureau of Investigation and the FBI.

Memphis and university police said Fletcher was forced into a dark SUV after a brief struggle. Police said the vehicle appears to be a dark-colored GMC Terrain.

Fletcher was reported missing at about 7 a.m. Friday.  The FBI and Tennessee Bureau of Investigation joined the investigation and law enforcement released grainy images of Fletcher running and the dark SUV believed to be the one she was forced into. Fletcher, who is 5′ 6″ tall, weighs 137 pounds, and has brown hair, was wearing purple shorts and a pink sports bra.
