The attorney for Laquanta Chapman claims the interviews conducted following his November 2008 arrest on gun and drug charges violated Miranda rights.
Authorities say Chapman butchered dogs in the basement of his Coatesville home to cover up the killing and dismemberment of 16-year-old Aaron Turner, who disappeared a year earlier. His body was never found.
The Daily Local News reports police testified Friday Chapman waived his right to have an attorney present. The judge did not immediately rule.
A second man has already pleaded guilty and is expected to testify.
