The two executed men had been in prison since April 7, 1995. Muslim Filipino cellmates reported them to guards for conducting Bible studies and praying with other prisoners.

Filipino Christian Rene H. Camahort, who remains in the prison, wrote in a letter after the decapitations that Janda had not been deterred by Saudi laws forbidding Christian prayer.
