A renowned lawyer was found shot dead in his house in Shahbaz Colony, Khairpur, on Saturday.
Police reached the spot and shifted the body to the Khairpur Civil Hospital.
A revolver was also recovered from his bedroom.
The B-Section station house officer (SHO) said that an investigation was underway to resolve the mysterious death of Zeeshan Hyder Sial.
