But the account from the family and the one that the police were first given are very different - which has led investigators to be suspicious.
According to communications officer, ASP Fitzroy Yearwood, they were first told that the child had inserted something into an outlet, but when police got to the scene, that story didn't add up.
Here's what he explained to us today:
ASP Fitzroy Yearwood, Communications Officer, Belize Police Department
"He was at the neighbor's house playing and the mother and father were at home when they heard a loud scream. They are saying that when they went over there, they saw the mother of the house holding the baby in her hand, where she explained that he put some sort of wire into an outlet. The baby was rushed to the Karl Heusner Memorial Hospital but was pronounced dead. When our investigators went to the scene, this wire that was allegedly used was found somewhere at the back of the house. One, we are investigating why they removed something that they claimed may have cost this child his life. And so, for me to go in-depth, I would have to get their final findings sometime today and then I can relay that to you."
While this is still a death investigation, ASP Yearwood says they will determine at the end if any charges are to be levied.
As for the power connection - these residents say they have not been able to get proper electricity connectivity. So, they had to improvise to get power for essential needs. We have checked with informed sources on the topic. They tell us that while sharing electricity between houses in this manner isn't illegal in the strictest sense, it is hazardous, as the case of Little Marvin Lopez painfully demonstrates. Therefore, that type of connectivity is strictly discouraged. We understand that a team from Belize Electricity Limited will be conducting their own investigations into Marvin Lopez's death.
