Prince George’s County Police recently announced the arrest of William Pavon Mancock, who is charged with first-degree murder and a host of related crimes for a brutal act of violence.

According to court documents, the murder happened in a now-abandoned homeless camp behind 9205 New Hampshire Avenue. Police said a witness told them an MS13 gang member known to them as “Contrachita” got into an argument with another man, pulled out a Uzi machine gun, shot him in the chest then shot him again and again on the ground.

Detectives heard from more tipsters who said that Contrachita was Pavon Mancock.

Now, 7News learned that the Honduran national entered the United States illegally and remained in the country despite several arrests.

According to an Immigrations and Customs Enforcement spokesperson, Pavo-Mancock was stopped by the U.S. Border Patrol after illegally entering the U.S. at the Mexican border in 2017. He was then released by ICE into the U.S. on May 10, 2017.

He was arrested for a stolen car in Montgomery County in October 2023. An ICE detainer wasn’t honored by the county and he was released.

Then, in November of 2023, he was arrested on a drug charge in Anne Arundel County. After 57 days in jail, he was released and was free until his arrest for the murder in Prince George’s County on Oct. 5. A new detainer has now been filed.

Pavon-Mancock is being held without bond in the Prince George’s County detention center.
