Cox, 27, of Mammoth was brought to Fulton County Jail by Fulton County deputies Bruce Green and Terry Walker after waiving his right of extradition in Illinois.
Cox made his first appearance in front of District Judge Jim Short April 3 at the Fulton County Jail. Cox is charged with arson, a class B felony, and first degree attempted murder, a class A felony. Bail is set for $50,000.
The charges stem from a March 17 incident at the Salem home of his then girlfriend, Denise Pawloski.
Authorities said Cox and Pawloski had been arguing a few minutes earlier which resulted in both Pawloski and Cox leaving the premises. Pawloski's sister, who was at a neighbor's home, said she witnessed Cox return and crawl through a window in the home, then leave through the front door. Pawloski, her sister and her 14-year-old daughter arrived at the home shortly after and found smoke coming from the home, which authorities said was a result of a fire set in a closet.
Authorities said Cox fled to Illinois after the incident, where he appeared at his father's home. His father told him to leave the property and contacted Peoria County authorities, Fulton County Sheriff Walter Dillinger said.
Cox was later found and arrested at a Caterpillar plant in Mossville, Ill. He was kept in the Peoria County Jail until Fulton County deputies brought him back to Arkansas.
