Marni Yang's ex-boyfriend testifies in trial

March 9, 2011 (CHICAGO)

Yang is charged with murdering Rhoni Reuter, who was pregnant with the baby of former Chicago Bear, Shaun Gayle.

Salvador Devera testified Yang gave him a book for his birthday on how to make gun silencers just two weeks before Reuter was murdered. He said he worked security with Yang at a Chicago Bears fan convention back in 2005 where Yang met Shaun Gayle.
