A MONTGOMERY COUNTY man accused of killing a baby and her grandmother in a botched ransom kidnapping wants to prevent a jury from seeing key prosecution evidence.

Published reports said attorneys for Raghunandan Yandamuri, 27, were in Montgomery County Court yesterday asking to have a videotaped confession suppressed should the case go to trial.

Prosecutors said the defendant describes in the video what happened to 10-month-old Saanvi Venna and her grandmother in October 2012.

Authorities allege Yandamuri kidnapped the baby from her family's King of Prussia apartment and killed her grandmother who tried to protect the child. The girl's body was found several days later.

Prosecutors are seeking the death penalty.
