Is singer the cause of Earl Hayes/Stephanie Moseley murder?

Singer Trey Songz may have caused the lives of hip-hop couple, Earl Hayes and Stephanie Moseley.

Stephanie Moseley who starred in VH1's "Hit the Floor", was shot dead by her husband Earl Hayes before killing himself on Monday in their Los Angeles apartment.

Now, the man whom the police claim shot his famous wife to death and then took his life was haunted by her alleged infidelity. One name that has popped up is Trey Songz whom some say he said had a fling with his wife in the past.

According to TMZ, sources connected with Hayes revealed that around 2 years ago, he separated from Stephanie because of [what he said was] her affair with Songz. They got back together but, as one friend puts it, "He was crushed and never got over it" and frequently brought up Songz' name in their fights.

Hayes accused Moseley of having multiple affairs with various other entertainers. She was a backup dancer who worked with numerous famous singers, including Chris Brown and Usher, but Hayes never mentioned them as a source of conflict.

Hayes and Moseley married in 2008 and his friends say he loved her and tried rationalizing staying together.

Trey is still to comment on the new development but he however droped a condolence message on his Twitter, writing:

"R.I.P babygirl. Once an angel on earth, now watching over us from heaven. You'll be missed but never forgotten. Love."
