Where did you get the length of the calls info?
Someone mentioned text messages: definite possibility.
Re: calling to see if anything else was going on - most students probably were not in town - spring break.
But, you never know.
Abrams stated the logest call was 36 seconds, but I may have misunderstood. I'll listen again and verify he said that.
Yep, that's what Abrams said. He said it in the context of a discussion about the calls as an alibi and stated that the longest call between 12:05 and 12:13 was 36 seconds.
