CHICAGO -- Police in Chicago found six people dead inside a single home in the city's Gage Park on Thursday afternoon.
The investigation is still in its infancy and authorities said they don't know much just yet.
But it appears they discovered a grisly scene: The bodies showed signs of trauma and were found in different places throughout a single-family brick bungalow, interim police Superintendent John Escalante said.
One of them belonged to a child, probably between 10 and 12 years old.
"This is going to be an investigation that's going to take some time," Escalante said at a news conference in front of the house. "We haven't ruled out anything at this point."
Despite the macabre discovery, Escalante says police don't believe neighbors should be worried. Authorities are adding additional patrols in the area as a precaution, however.
Detectives in the neighborhood and crime lab personnel are working to identify those killed, but Escalante acknowledged it is "very probable that this is all the same family inside."
"There is a very real possibility that this is something all internal that was contained within the residence," he said.
Still, many in the working-class community in southwest Chicago are shocked.
"Everybody is just pretty much upset and scared," Markita Williams, who lives next door to the house where the bodies were discovered, told CNN over the phone.
"It's just one of those things I can't explain. Good family, good kids," she said. "I just don't know."
On Wednesday, Williams said she noticed that a van belonging to her neighbor was on the street. The city was doing some work, and she worried that the car would get towed.
She went up to warn the family and saw the blinds were shut.
"Everything was closed up tight," Williams, who has lived directly next door for three years, said. "They always had their curtains open -- you could see directly into the house from the front and on the side."
She knocked on the door. No response.
Police showed up the next day. One of the residents failed to show up for work two days in a row, so a co-worker called 911, according Escalante.
Rosa de la Torre told CNN affiliate WGBO that she was friends with one of the victims.
"[She was] a good person, very happy," she said in Spanish.
Police came to Williams on Thursday and asked her if she'd look after Maria, the neighbor's dog.
Maria looked shaken up and hungry. And she had blood on her.
So they took her in, cleaned her up and fed her.
"I don't really do dogs, but you know, we're really trying to care for her," she said.
A GoFundMe account set up for the surviving family members says the following:
On February 4th 2016, the bodies of Rosa Hernandez, Noe Martinez, Noe Martinez Jr., Herminia Martinez, and Herminia’s two young sons Alexis and Leonardo were found in their home, where no member survived. This has shocked and left their family, relatives and loved ones speechless and heartbroken as the household was nothing but a loving and gentle family that was always quiet. In the time of need the family asks for help in both prayers and donations to help send the bodies back to Mexico, where they would’ve wished to be buried. The donations given will help send the bodies to Mexico and help with the funerals and burying ceremonies of all six members. God bless everyone, every little bit helps and is appreciated greatly.
