STORRS, Conn. — Witnesses to the killing of University of Connecticut football player Jasper Howard are being threatened with violence if they come forward with evidence, campus police say.

Maj. Ronald Blicher told the student newspaper, The Daily Campus, that the threats were being made in Internet postings and that police were looking into them. He said authorities were still urging people to submit videos, photos or other information.

Howard, a Miami native and starting cornerback for the Huskies, was stabbed outside a university-sanctioned dance early Sunday, hours after helping his team to a homecoming-game win over Louisville.

A 21-year-old Hartford man, Johnny Hood, has been arrested in connection with the fight but is not charged with stabbing Howard.
