Anthony Eugene Brown, 28, of Rubidoux and a 16-year-old boy were arrested at the Horseshoe Motel at 12:30 p.m., Reno police Sgt. Doug McPartland said.

Brown and the boy are charged in the slaying of Jamaloddin Doroudi, 46, of Rubidoux, Riverside County sheriff's officials said. The two are being held without bail at the Washoe County Jail in Reno.

Authorities have not released the boy's name because of his age. Riverside County district attorney's officials are determining if they will seek to try the teen-ager as an adult.

The third person charged in the killing, Melissa Sue Rogers, 21, of Rubidoux, was arrested Thursday and is being held without bail at the Robert Presley Detention Center in Riverside.

The suspects are accused of handcuffing Doroudi inside his 99-cent store in Rubidoux and then shooting and stabbing him to death before taking an estimated $20,000 in cash, officials said.

Riverside County sheriff's spokesman John Kaiser credited the homicide unit's work with the FBI in leading to Friday's arrests.

Kaiser said investigators contacted the Reno FBI office Friday morning after developing leads the suspects were in the city.

A patrol officer spotted the Chevrolet truck being sought by Riverside sheriff's investigators in the parking lot of the motel, McPartland said. Authorities staked out the motel and arrested Brown and the boy as they left their room, he said.

No weapons were found with the two suspects, officials said.
