An FBI agent has testified that he could not say whether agents have found ricin in the home of a Mississippi man accused of mailing the toxin to the president and a senator.
Agent Brandon M. Grant testified at a hearing Friday in Oxford, Miss., for Paul Kevin Curtis. Testimony ended Friday evening, but the hearing was to continue Monday morning.
Grant stressed that the investigation is ongoing and that he does not know what may have been found with the hearing approaching two hours long. He says investigators searching the home did find a package they were interested in. But he did not yet know what was in it.
Grant says investigators are looking at the possibility that others were involved, but he says Curtis is the primary suspect.
