Father who 'stabbed wife and daughters to death before hanging himself researched how to cut someone's throat beforehand'

A father who stabbed his wife and daughters to death before hanging himself had researched how to cut someone's throat beforehand, an inquest has heard.

The bodies of Jitendra Lad, 49, his wife, Dukshaben, 44, and their daughters, Trisha, 19, and Nisha, 16, were found at their four-bed detached home in Clayton, Bradford, last October in what a coroner described as a "scene of unimaginable horror".
