Caleb Fairley (born October 21, 1973) is an American murderer from Gulph Mills, Pennsylvania. In September 1995, Fairley murdered Lisa Marie Manderach, aged 29, and her 18-month-old daughter Devon, when the two visited Fairley's mother's Collegeville, Pennsylvania children's clothing store in which he worked. Crime On September 10, 1995, Fairley was working alone at Your Kidz & Mine, the Collegeville children's clothing store owned by his parents. Just before closing time, Lisa Marie Manderach (born September 30, 1965) and her daughter Devon (born February 4, 1994) entered the store. When Fairley realized that they were the only customers present, he locked the doors to the store. He then attempted to sexually assault Lisa Manderach. When she resisted him, he became enraged and strangled her to death. He also strangled her infant daughter. After the murder, he sexually abused Manderach's corpse, then went to an Electric Hellfire Club concert that he had been planning to attend that night. Arrest and trial Lisa Manderach had told her husband where she was going. When she did not return home, he contacted local police, who found her car parked outside the store. A search of Your Kidz & Mine revealed stacks of pornography stained with what appeared to be blood and long black hairs consistent with Manderach's. Similar hairs were found in the store's vacuum cleaner. Also present was a large damp spot on the carpet that was later determined to be saliva. The police also noted that peepholes had been drilled into the dressing rooms. Fairley was charged on September 12, 1995 with the murders of the mother and daughter. When police questioned Fairley, he was wearing a thick coat of makeup on his face. When detectives told him to wipe it off, his face was covered with scratch marks. When they were pointed out to Fairley by authorities, he said he received them in a mosh pit while attending an Electric Hellfire Club concert, at a local club called the Asylum. When hikers discovered Devon Manderach's strangled body dumped on a hill at Valley Forge National Park, Fairley was charged with two counts of murder and one count of abusing a corpse. Fairley entered a plea bargain in which prosecutors would not seek the death penalty if he would show them the location of Lisa Manderach's body. Fairley upheld his end of the bargain. Fairley was tried in April 1996 and convicted
