UP police done very worst job.They not taken quick action to solve the case and not considered all clues.It's around 1 month completed.Maybe all proofs,things r destroyed by criminals.the case is getting very complicated as all proofs,suspects not considered in proper time,delay in this case is problematic for CBI. Police told about Arushi's relation with Hemraj,but it's quite impossible that 14 yrs old educated girl had relation with 42 yrs servant.And police also told that her father saw them in compromising position at night.None Indian girl would be in such a position when her parents r present at home.But,Talwar family may be involved in both the murders as two murders happened in same house and they couldn't hear any sound,it's impossible.
