Prosecutors in California have charged two sons with murder in the killing of their parents.

Sean Webby, public communications officer for the Santa Clara County district attorney's office, said 22-year-old Hasib Bin Golam Rabbi and his 17-year-old brother will be arraigned Friday.

The minor will be charged as an adult, but Webby did not have his name.

Shamima and Golam Rabbi were found shot to death Sunday in their home on a quiet cul de sac in San Jose. The double slaying and the arrest of the sons Thursday have horrified the tight-knit Muslim community.

A prayer service is planned for the parents Friday afternoon.

The older son told the San Francisco Chronicle in a jailhouse interview Thursday that he is eager to tell the real story but offered no other details. He emphasized that his brother is innocent.
