The mistery case of a baby in Chia!!!!!

In september, 2008, a little baby named Luis Santiago was reported as missing, since then, his parents started a  seach with the help of the police, other authorities and all the people.
He was only 11 months,  they tried to find their baby  as fast as posible , but some hours later, an  informant told something to the uthorities due to an reward,  by that time, it was 20 million. Before that, it was thought that this case was a revenge with his mother or a kidnaping because his father had gotten a loan for 8 millions pesos.
The informer said that the father asked  him to take the baby for $300.000, the father offered 200.000 pesos more later to the same man, but he did not agree.
A second informer said that the father propoused him to  kidnap the baby, then, there was another similar version and the police started to think seriously in the father as the responsable of this case.
He was interrogated and there was many contradictions about places and times; trhee days after the disappearance, the baby was found died, and as police was thinking, his father was the author of this crime, although being in the streets searching for his child and asking for help to the rest of the country, it is anbelievable but he killed his own child.
