Police probe on for Cho's confidants

WASHINGTON: New court documents show US police are probing the possibility that Cho Seung-Hui may have confided to someone else his plans to unleash a massacre at Virginia Tech University, ABC News reported on Friday.

The shooting Monday, deemed the worst of its kind in US history, left 32 students and teachers dead.

The network said that in a search warrant affidavit filed by Virginia State Police on Friday, authorities say the shooter 'may have communicated with others concerning his plans to carry out attacks on students and faculty at Virginia Tech.'

Police are now seeking Cho's cell phone records from Verizon Wireless in New Jersey, according to the report.

In another warrant affidavit filed on Friday, police seek to mine Virginia Tech's computer servers, to see if Cho may have communicated by email with Emily Hilscher, one of two victims shot in Ambler Johnston Hall, ABC News said.

The affidavit says that 'there is probable cause to believe the computer information maintained by Virginia Tech for Cho Seung-Hui and victim Emily Hilscher, may contain information relating to so cites a criminal investigative analyst who tells police that in 80 to 85 per cent of homicide cases the victim is known to the offender," the network said.
