She stands about 4-foot-5 and weighs 95 pounds. She has black hair and brown eyes.
Guerrero-Torres was in court, Monday afternoon, where he was charged with possessing child pornography.
Scripps station WFTX spoke with Diana's cousin, who said the family doesn't know what to make of the charge. "We don't want to imagine the worst case scenario, again, we want to try to stay positive," said Nancy Martinez.
Documents show that authorities reviewed Guerrero-Torres' cell phone records, which show on the evening of May 28, 2016 he left his residence in Orlando and headed to the Fort Myers area. The phone records also show he was near the home of Diana Alvarez between 12 a.m. and 3 a.m. on May 29, 2016 - the day she was reported missing by her parents. Guerrero-Torres then left Fort Myers early in the morning of May 29, 2016 and headed towards Okeechobee spending several hours near Yee-Haw Junction.
Documents also show that police found graphic photos of a child on Guerrero's phone. It's unknown if the 9-year-old is in the photos. Police tell us Jorge Guerrero-Torres will remain in federal prison at this time. The investigation into the disappearance of Diana Alvarez remains active, however, Alvarez' name was not mentioned in Monday's court proceedings.
If you have any information on where deputies can find Diana, you are asked to call the Lee County Sheriff's Office at 239-477-1000 or 911.
