Sons Arrested For Parents Murder

A relative said the siblings had gone to Oakland, California, on Saturday morning and were not around when their parents' bodies were discovered.

The bodies of Golam and Shamima Rabbi were found at the weekend in their San Jose property. Each had been shot at least once.

Hasib Bin Golamrabbi, 22, and his 17-year-old brother, a high school student, were both detained on Wednesday, police said.

The older brother, who is reportedly a San Jose State University, was missing until taken into custody Wednesday night, said authorities. 

A motive for the double homicide remains unclear.

But sources told NBC Bay Area the parents did not approve that the older son was gay.

Mr Rabbi, 59, worked as an engineer and Mrs Rabbi, 57, was employed as an accountant.

Their funeral is scheduled for Friday.

Hasan Rahim, a board member at the Rabbis' local mosque, the Evergreen Islamic Center, told the TV station: "I can't believe it."

He described both sons as "taciturn" and "not very communicative". 

The Rabbis were discovered on Sunday afternoon by friends who came to check on them.

A message written in ink on the hardwood floor beside their bodies said: "Sorry, my first kill was clumsy."

Another message said: "I can't be like you, telling a lie. I can't love someone without telling them."

The couple emigrated to the US from Bangladesh decades ago.
