(CNN) Faye Marie Swetlik, a South Carolina 6-year-old who went missing from her home, was abducted and killed by a neighbor who died by suicide, authorities said Tuesday.

The first-grader died of asphyxiation hours after she was abducted last week in Cayce, Lexington County Corner Margaret Fisher said, citing the results of a recent autopsy.

The girl was last seen playing in her front yard on February 10 after taking the bus home from Springdale Elementary School, Cayce Department of Public Safety Sgt. Evan Antley told reporters. Her body was found February 13 in a wooded area between her family's house and an auto parts store, according to Antley.

Authorities released the results of the girl's autopsy and details of the investigation that led them to the suspect in her death. That suspect, Coty Scott Taylor, 30, was found in his residence about 150 feet from the Faye's house shortly after her body was discovered.

"Evidence leads us to believe that the deceased abducted and killed 6-year-old Faye Marie Swetlik," Cayce Director of Public Safety Byron Snellgrove told reporters.
