A fourth suspect was arrested and charged Thursday in the killing of a 14-year-old girl in Prince George's County in April.
Edwin Rios, 18, of Southeast D.C., faces first-degree murder and related charges.
Rios is the last of the four suspects police believe were involved in the slaying of Ariana Funes-Diaz, the teen whose body was found in a creek by police cadaver dogs after one of the other suspects tipped investigators on the location.
Three other teenagers have been arrested and charged in the killing. Police said two of the three are suspected MS-13 members.
Josue Fuentes-Ponce, 16, Joel Escobar, 17, and Cynthia Hernandez-Nucamendi, 14, are all suspected in the killing of Funes-Diaz. Police said the teen was killed in a wooded area behind an apartment complex on 64th Avenue on April 18.
The chief medical examiner's office in Baltimore said the girl sustained significant head trauma and died from multiple injuries.
According to charging documents, Hernandez-Nucamendi told investigators where to search for Funes-Diaz's body. The documents said Hernandez-Nucamendi also described in more detail the premeditated killing of Funes-Diaz, telling investigators that the victim was beaten with a machete as well as a baseball bat. She told police Rios recorded the deadly attack with his phone, according to documents.
Funes-Diaz and Hernandez-Nucamendi were reported missing in April and police said they ran away from Anne Arundel County.
Fuentes-Ponce, of Bladensburg, and Escobar, of Northeast D.C., are suspected members of MS-13.
The first three suspects were arrested and charged with first-degree murder and related charges. Escobar and Hernandez-Nucamendi are in the custody of the Department of Corrections on a no-bond status. Ponce is in custody at the Cheltenham Youth Detention Center.
