Authorities in Texas say a man has confessed to the murder and dismemberment of a former friend, whose remains were found by a hiker in a Florida national forest earlier this year.

According to the New York Post, the body parts were identified as 62-year-old Robin Lee Upson after officials confirmed she had a distinguishing tattoo on her torso that matched one found on the remains.

After speaking to family members of the deceased, investigators determined 43-year-old Christopher Lee Takhvar had borrowed the woman’s van prior to her death and had not returned it to her. The man and woman had been friends and business partners, according to media reports.

Police in Jefferson, Texas, arrested Takhvar on suspicion of killing Upson at her home in Belleview, Florida, and transporting her remains to Ocala National Forest in the victim’s vehicle.

The van was later recovered in Orlando and Takhvar was initially arrested on a warrant accusing him of stealing the vehicle.

After his Aug. 15 arrest, he reportedly told authorities that he killed Upson in self defense, using a chainsaw to thwart her attack with a knife.

He also allegedly told authorities that he transported the torso to the forest and buried her head, arms and legs in the backyard of the victim’s home. Reports indicate the body parts have been recovered.

Following his arrest, Takhvar was subsequently charged with murder in addition to grand theft auto.

As of the latest updates available, bail was denied and the suspect remained behind bars at Marion County Jail.
