Nearly a year after pianist Karan Joseph's unnatural death, his father Thomas Joseph wrote to Mumbai Police in the first week of August, 'pleading for the feedback on forensic and progress in the case'. "Mumbai Police got a very long time to investigate the matter, but nothing has come of it so far. So we have written to the commissioner and copied the letter to the joint commissioner of police (crime). Now, we are waiting for the reply. We want to know what the forensic results were," Dr Thomas told mid-day. In his letter, Thomas raised serious doubts on how Karan's cellphone escaped damage after he allegedly fell off the 12th floor of Concorde Apartments in Bandra West on September 9 last year.

The offices of Mumbai Police Commissioner Subodh Jaiswal and Joint Commissioner of Police Ashutosh Dumbare, received the four-page letter last week. Dumbare told mid-day, "We are working on all the doubts raised by his (Karan's) father. His father suspects that the cellphone was planted by prime suspect Rishi Shah."
