A series of music videos introduced as evidence into the coroner's inquest of the Fredy Villanueva police shooting have put older brother Dany's credibility in question.

Hip-hop videos featuring Dany Villanueva shown in court Wednesday proved he was associating with known gang members, contradicting earlier testimony he had quit gangs as far back as in 2006.

Police are trying to undermine Villanueva's credibility on the witness stand at the coroner's inquest into Fredy Villanueva's death, a teenager shot dead in front of his brother during an intervention by police in Montreal North in August 2008.

Lawyers for the Montreal police said Dany's testimony can not be believed because he is a known criminal, with an adult record dating back to 2005, at age 18.

The videos show Dany with Montreal North hip-hop group Mobsterz.

The words in the songs glorify gangs and gang members associated with the "Reds", or "Bloods," an umbrella group for many criminal street gangs. A second video also features known gang members with whom Dany Villanueva wasn't supposed to be in contact

Police insist his version of the shooting is not to be believed.

Villanueva's family argues the attack on his credibility is proof police try to protect their own, by shifting the blame on the victim and his brother.
