Police in Las Vegas are investigating the gruesome death of a teenage girl whose burned body was found tucked away behind the walls of an apartment complex.

According to the Las Vegas Review-Journal, Las Vegas Metropolitan police officers responded to the apartment complex just after 11 a.m. on March 11 after receiving a report of a dead body.

Two residents of the apartment complex who were testing out their drone called 911 after they noticed unusual black marks up and down the walls of the complex.

First responders confirmed the marks led to the burned body of a young girl. The body had been tucked between two walls in a hidden corner of the complex, the Las Vegas Review-Journal reported.

“It’s pretty gruesome,” Metropolitan Police Department Lt. Dan McGrath told the newspaper. “We don’t have a lot of information, but we have a very petite young girl who is dead.”

Police have not announced a precise cause of death, but authorities believe the girl’s body was dumped and set on fire after she was killed. Investigators told the Las Vegas Review-Journal that there were visible signs of an accelerant having been poured on the body.

The victim, who has yet to be identified, is described as a light-complexion black female standing 5’4” tall and weighing approximately 100 pounds. Police believe she is between the ages of 16 and 20.

Investigators, who continue to search missing person and runaway reports with the hopes of identifying the girl, have released a sketch of what she may have looked like.

“The faster we identify her, the faster we’ll be able to figure out who she was with, who she associated with, and who might have done this,” Lt. McGrath told the newspaper.

Anyone with potential information is urged to contact the Las Vegas Metropolitan Police Department’s Homicide Section at 702-828-3521 or Crime Stoppers at 702-385-5555.
