Some of the key events Tuesday in the O.J. Simpson murder trial:
* SUMMARY: Two police officers testified about the handling of the crime scene, even as new allegations were raised about jurors in the case. According to sources, at least one juror is being investigated for allegedly expressing views about the case's outcome while another came under fire for looking at pictures in Simpson's house. A Sheriff's Department investigation into another allegation--that a juror was found with a map of crime scene landmarks--had been concluded and that juror will be allowed to remain on the panel, sources said.
* WITNESSES: On the stand Tuesday:
* Officer Robert Riske: Concluded nearly two days on the stand by telling jurors it was not his job to photograph or collect evidence.
* Sgt. David Rossi: Testified that the crime scene was secure by the time he arrived about 1:30 a.m. June 13. On cross-examination, said he had not seen footprints alongside a walk where the bodies were found, despite the fact that other officers had already passed that way.
