The body of Saanvi Venna, the 10-month-old girl who disappeared from the Marquis Apartments in King of Prussia on Monday following the murder of her grandmother, was found at about 4:30 a.m. Friday in a sauna room inside the apartment complex, Montgomery County District Attorney Risa Ferman said.

Raghunandan Yandamuri, 26, described by Ferman as a friend of the Venna family, has been charged in the murders of Saanvi and Satyavathi Venna. Ferman said Yandamuri told authorities that he intended to kidnap the child and hold her for $50,000 ransom. See this article's photo section to see a copy of the ransom note.

"He believed the family was of sufficient means to pay that ransom," Ferman said. As he was leaving the scene of the elder Venna's murder, Ferman said, Yandamuri "suffocated" the baby with a handkerchief and placed her in a suitcase, later disposing of the body.

The chillingly detailed ransom note allegedly left by Yandamuri threatened that Saanvi would be "cut into pieces" and have her body parts "thrown into your apartments" if the family informed anyone of the abduction. Ferman said that Yandamuri also lived at the Marquis apartments and had known the Venna family "socially" since the summer.

Ferman said authorities believe that Yandamuri did not initially intend to kill the victims and that he had appeared as a support figure for the family in the days since the killing, going so far as to post "missing" flyers for Saanvi Venna.

According to an affidavit filed by Upper Merion Detective Andrew Rathfon and Montgomery County Detective Paul Bradbury, the use of the Indian diminutives "shiva" and "lata" in the ransom note helped lead authorities to believe that the note's author was someone familiar with the family. Authorities first interviewed Yandamuri on Thursday, the day after he attended a vigil held in support of the family. He initially denied being involved in the killings but later admitted to them, the affidavit states.
