In 2011, Mahipal Maderna was accused of being involved in a case relating to the disappearance of a nurse named Bhanwari Devi. Bhanwari, who worked as an auxiliary nurse/midwife in the Jaliwada village went missing on 1 September. Her husband Amarchand alleged that she was abducted on orders of Maderna. Subsequently, the Chief Minister Ashok Gehlot sacked Maderna as a minister on 26 October. It was alleged that Bhanwari Devi was negotiating a multi-crore deal with Maderna and his opponents to trade of a CD in which she was seen in a "compromising position" with Maderna and others. In November 2011, Rehana, the girlfriend of the key suspect Shahabuddin, leaked an audio clip to the reporters. The clip was recorded during her discussion with Shahabuddin in the Jodhpur Central Jail. In the clip, Shahabuddin is heard telling Rehana that Bhanwari Devi was handed over to the gang of Pradeep Godara, a criminal wanted by the Rajasthan police in several cases. He is also heard telling that he had been falsely implicated in the case, and had no clue what happened to Bhanwari. CBI arrested Maderna on 3 December and questioned him. He was confronted with the key suspects, Sahiram Bishnoi, Shahabuddin and Sohan Lal Bishnoi in jail. Later it was revealed that maderna and Congress legislator Malkhan Singh were hand-in-glove in the entire conspiracy as the nurse was blackmailing both of them. The two politicians allegedly roped in a Sahiram Bishnoi, who hired Sohan Lal, Balia and Shahabuddin for the task of kidnapping the nurse. On 6 January Central Bureau of Investigation claimed to know whereabouts of disposal of Bhanwari Devi's body. Investigating officers were praised by Central Bureau of Investigation director for solving this case in 100 days. The agency is about to file a second charge sheet after admission of the Bishnaram gang on the disposal of bhanwari devi's body at Jaloda village near Osian village in Jodhpur.
