Medina was a part time actor on the USA Network show Burn Notice .

The wannabe star boasted online about his tiny bit-part appearances and dreamed of fame that he never quite attained. He appeared only as a backgound extra with his head-shaved and pouting in two episodes in 2010.



However, that didn't stop his talking up his achievements.



Posting a video on You Tube, he narrated: 'Put on USA, I’m coming out on the episode right now. I’m on USA. I’m going to come out soon. This is the episode that I filmed. hat’s me right there! You saw me?'

‘He just said that his wife picked up a knife on him, and they had a big fight, and he shot her,’ said the father.

Derek Medina Sr said that girl who was removed from the apartment wrapped in a blanket is Alfonso’s daughter from a previous relationship.



According to the father, his son had a rocky relationship with Alfonso. He said that the two got a divorce after being married for three years, but tied the knot again last year.
