Dahiya had joined the probe after being approached by CBI in 2009.

Mir said that as per Dahiya's report, the crime was the result of “grave and sudden provocation”.  

Dahiya had during his statement told the court that the crime was possibly committed using a golf club and surgical knife, and that no outsider except the Talwar couple was involved in the murder.

Dahiya had also said that the two (Aarushi and Hemraj) were murdered in Aarushi's bed.
