State v. Lasaga
In State v. Lasaga (2004) 269 Conn. 454 848 A. 2d 1149 a systems administrator, working on information supplied by a student, monitored a professor's computer and discovered that the latter was downloading child porn. (Id. at pp. 456-457.)
After speaking with his supervisor and the university's lawyer, the administrator went to the police, and a search warrant was obtained based on the information the administrator had gathered before going to the police.
The Connecticut Supreme Court concluded that the administrator was not an agent for the police because the police did not seek him out and were not involved in his decision to monitor the professor's downloads, and he had not had a previous relationship with the police and was not being compensated by them for his efforts. (Id. at p. 466.)
