Burnt CA student: Was it a suicide or a plain murder?

A young CA aspirant was found completely burnt near the IAS quarters in Hyderabad last Thursday. But, was it suicide as claimed by the cops or was there any thing more than meets the eye in the gory end of the beautiful young girl?

Poojita Vasireddy's burnt remains were found near the swank IAS colony in the busy Banjara Hills area. A suicide note was found in her room, which said she was taking her life as she couldn't clear the CA IInd year exams. Based on this the police said the death was a case of plain suicide.
But, Poojitha's parents refuse to take this argument. They says it was a murder and that the cops were trying to suppress the facts. They alleged that she had come to Hyderabad with a banker, who hails from Bihar. The said banker is the son of an officer with Bihar police. The parents allege that the Telangana police were trying to hide the facts to save the son of a police official.
The police however, said the probe was on and every angle was being looked into.
