One of two suspects in a weekend double homicide and child abduction was expected to be arraigned Monday in Massachusetts.

Malcolm Crowell, 22, was to appear on a fugitive-from-justice warrant, according to the clerk's office at Fall River District Court.

Crowell and Daniel Rodriguez, 27 or 28, were arrested Sunday in the two slayings and the abduction of 2-year-old Isaiah Perez, who was later found unharmed after a nationwide Amber Alert was issued.

The bodies were discovered about 5:20 a.m. Sunday at a home in suburban Johnston, a town of 30,000 residents less than 10 miles from Providence. The names of the dead were not immediately released, but Johnston Police Chief Richard S. Tamburini said one of the victims was the child's mother.

The boy was found around 8:15 p.m. in Providence after a police officer there spotted him walking around a housing project by himself.

Deputy Police Chief Daniel Parrillo said it was unclear whether the boy's abductor was living in the home, was a guest or was uninvited.
