Police say this shirt was found on the boy , dubbed `` Baby Justice '' or `` Baby Angel . '' It led police to the body of a young boy , who had been buried there in a shallow grave less than 48 hours earlier . That was Friday . On Tuesday , police still had no answers as to what happened at Alvarado Park -- or even who the boy was . His name is unknown , though the community has dubbed him `` Baby Justice '' or `` Baby Angel . '' Nobody in the area has claimed his body and nobody has reported a child of his age missing . Police said they could n't even show a photo or give a sketch of the boy because his body was so disfigured by the sand 's heat . All they have is a description based on how they found him . Police say the Native American or Hispanic boy was between 3 and 5 years old , 38 pounds , 38 inches in height , with brown eyes and dark quarter-inch hair . When he was found , he was wearing Arizona brand clothing , size 3T -- nylon black running pants with red stripes , a red shirt with a monster truck on it and black , gray and lime green Skechers sneakers . Police are n't sure how he died . Albuquerque Police Department Spokesman John Walsh said a preliminary autopsy did n't reveal a cause of death . Walsh said there were no obvious signs of bruising on the boy . Watch where boy was found buried » . Walsh said the department is working with the National Center for Missing and Exploited Children to create a forensic reconstruction of what the boy may have looked like in hopes that someone will recognize him . `` We have canvassed the entire adjoining neighborhood , '' Walsh said . `` We 're knocking on every door . We 've been broadcasting and pleading for tips from the community . But still , nobody has come forward . '' Watch authorities discuss boy in the sand case » . Though police have received numerous tips from the public , Walsh said nothing has come from them . Albuquerque police are working with other local , state and nationwide law enforcement officials to try to piece together what happened . Until then , members of the community have spent hours at memorials for the boy -- who none of them knew -- praying for him and raising money . French Mortuary , in the town , has offered to pay all funeral costs for the boy . Resident Rachel Lesperance told CNN affiliate KOAT-TV she spent her weekend collecting $ 3,600 for the boy . Her money , and the donations raised by others , will go toward a plaque at the park in the boy 's honor , buying extra lights for the playground and to a fund toward finding out what happened to the little `` Baby Justice . '' `` He does n't have a family , '' Lesperance told KOAT-TV . `` We 're his family now and we want him to be taken care of like one of our own . ''
