Police are investigating a small polygamist sect after two members -- a 5-year-old boy and a 28-year-old woman -- went missing.
Authorities believe they were killed by members of the group, but they haven't been able to find the bodies.
A Colorado search warrant obtained by WRAL-TV said a confidential informant told investigators that the boy, Jadon Higganbothan, was shot in October and his body stuffed in a suitcase.
The warrant also said a woman got into an argument with members of a religious sect called the Black Hebrews and was killed.
Both deaths happened in North Carolina.
Detectives in Durham, N.C. said the sect members then moved to Teller County in Colorado.
Teller County deputies visited the group on Feb. 23.
They did not find the boy or his mother, Vania Rae Sisk.
Deputies said they did find Sisk later that day at a Walmart. Sisk told police she left Jadon in North Carolina with a friend on Feb. 20.
An informant told police in North Carolina that Peter Moses, the leader of the sect, was angrily pacing the house in October 2010, called for Jadon, took him to the basement and turned on loud music, then a gunshot was heard, according to the search warrants.
The informant told police he later saw the boy's body wrapped in plastic, stuffed in a suitcase and placed in the attic of the home.
The warrants also said Moses gave Sisk a gun and told her to shoot a 28-year-old woman, Antoinetta McKoy, which she did.
McKoy's family said they haven't heard from her in months.
A warrant released Tuesday in North Carolina said authorities searched the Durham home where Sisk and Moses once lived, finding a bullet, shell casings and possible human blood. The document said Sisk and Moses participated in killing an unnamed adult and a juvenile.
However, the pair haven't been charged.
It is not known if Sisk is still in Colorado.
