Police have registered a case against unidentified persons in connection with the 35-year-old's murder.
Sidhraj Singh (18) - son of the deceased - told the police that when he returned from market on Friday he found his house bolted from outside, police said.
After he unbolted the door, he found his mother lying in a pool of blood with bullet injuries, he told police.
A profusely bleeding Preeti, daughter of former MLA of Panna, Veer Vikram Singh (Bhaiya Raja) was rushed to the hospital where she breathed last.
