Sources said Thursday that police want to speak with Joseph in connection with a shooting death last month.

Joseph, a second-round pick of the Cowboys last year, was involved in an altercation with a group of individuals that resulted in the death of 20-year-old Cameron Ray. One of the people involved in the altercation was wearing a YKDV necklace. Joseph goes by the name YKDV Bossman Fat.

Ray and his friends walked to their vehicle after the altercation as shots were fired from an SUV.

The Cowboys didn't say anything. Sources said that the team talked with Joseph and encouraged him to talk to the police about what he knows about the incident.

The detective told KDFW that Ray and three friends were in Dallas for a weekend and that they were not responsible for the incident that preceded the shooting. The man in the YKDV necklace is one of the people seen in the video.

Joseph played one season at Kentucky after starting his college career at LSU.

Jones played in 10 games and made two starts, and was credited with 13 tackles and two pass deflections.
