In the film "In America" did the character Mateo loose a son?

I don't think the movie give us an explicit answer.

The things related to Mateo's "kid" are:
1. There was a "satellite" thing hanging in his room. It was unusual for a man. It could be his kid's toy.
2. He cried immediately when the girls told him they lost their brother. However, Mateo could feel sorry for himself because he was dying.
3. There was a painting of pregnant black woman in his room, too.
