Police arrested a sixth suspect Sunday in the killings of three college students in Newark.

The 18-year-old suspect, Melvin Jovel, was charged in connection to the execution-style murder of Terrance Aeriel, 18; Dashon Harvey, 20; and Iofemi Hightower, 20. Aeriel's sister, Natasha, was shot in the head but survived and has helped police in the investigation.

Jovel was apprehended in Elizabeth early Sunday morning, where police say he lives. Authorities do not believe he is related to any of the other suspects.

About 10 officers from the Newark Police Department, Essex County Prosecutor's office and Immigration and Customs Enforcement made the arrest at about 3 a.m., prosecutors said.

Bail was set at $2 million by state Superior Court Judge Michael Ravin.

Jovel's arrest occurred about 24 hours after federal authorities in the Washington, D.C. area arrested 24-year-old Nicaraguan immigrant Rodolfo Godinez and 16-year-old Alexander Alfaro, his stepbrother.

Three other suspects - 28-year-old Jose Carranza, an illegal immigrant from Peru, and two juveniles - were already in custody. All are charged with three counts of murder in addition to other counts.
