This came up in one of the early motions by the defense and was discussed at one of the hearings before Judge Stephens. The defense was concerned about safeguarding the data on her computer, IIRC. Here we discussed why LE would even have her computer. There didn't appear to be a subpeona for it.

Among the items the defense is seeking is an analysis of the accuser's computer, which Nifong said was still pending, and records from the mental health facility where authorities took the woman before she told police she had been raped. The only record from the facility, Nifong said, is a single page from a log book he is still working to obtain.
Nifong issued two subpoenas asking Duke University to hand over the home addresses for all of the lacrosse players as well as two other people.(from June 8, 2006)
