Maharashtra Forensic Laboratory will soon complete the testing of blood samples of slain Anti-Terrorism Squad chief Hemant Karkare [Images] and two other police officers, who were killed in the terror attack in Mumbai last month, for alcohol content, laboratory sources said.

State FSL at Kailna said that it has received the blood samples of the officers, who were killed by the terrorists on November 26, and the results will be handed over to the investigating authorities.

State-owned J J Hospital's forensic experts had sent these samples to the State Forensic Sciences Laboratory, asking it to examine the blood samples of the three police officials who include sharp shooter Vijay Salaskar and Ashok Amte, for alcohol content and the request letter was dated November 27, hospital sources said.

According to senior forensic experts, in the normal course of investigation into terrorist attack, blood samples are not given to the labs. Not even the viscera are tested in such cases, where the reason of killing was well established, sources said.

Only the clothes and bullets are sent to the labs, they said.

Senior police officials said it was not essential for doctors to keep the blood of these officers for alcohol test, as it was clear that the three officers were killed by the terrorists while exchanging fire.
