Samuel Ebenezer Sampath, a 34-year-old homeopathic doctor, has been arrested for allegedly killing his girlfriend, 37-year-old Cynthia, four months ago at his rented Chennai flat. Cynthia had moved-in with Sampath to aid her now-deceased father's dialysis and was blaming him for his inability to save her father. Sampath used chemicals to mask Cynthia and her father's decomposing bodies' smell.
