Silas Thompson, of Twin Falls, Idaho, is hugged by his mother, Renee, after arriving at the Kansas City International airport from Haiti on Thursday.

KANSAS CITY, Mo. — American missionaries accused of child trafficking in the aftermath of Haiti’s earthquake returned home Thursday and urged the safe release of the two women left behind in a Port-au-Prince jail.

Four of the eight freed Americans landed Thursday at Kansas City International airport to cheers and hugs. They declined to speak to reporters, but their attorney, Caleb Stegall, read a statement in which they said they were thankful to be home.

“We hope and pray that our release will allow everyone to focus again on the dire conditions that remain in Haiti. People are still suffering and lack basic necessities,” the statement said, adding: “For those whose cases have not been resolved, we will continue to pray for their safe return.

The group’s leader, Laura Silsby, and her former nanny, Charisa Coulter, remained in jail in Haiti. Both arrived at a Port-au-Prince courthouse on Thursday to be questioned by a judge about their plans to set up an orphanage in the Dominican Republic. But the judge rescheduled the appearance for today after a translator failed to show up.

“Everything is going well,” Silsby told reporters. “I don’t know the exact day we are going to be free.”

Judge Bernard Saint-Vil said he did not release Silsby, 47, or Coulter, 24, both of Boise, Idaho, because the two had previously visited Haiti in December and planned even before the quake to open an orphanage. After the quake, Silsby rushed to pull together the rest of the group.

Silsby’s sister in Idaho, Kim Barton, said learning that her sister could not leave Haiti was difficult. “At this point, I don’t have any comment. I don’t know any more than you do,” Barton said.

The group was caught Jan. 29 trying to take 33 children out of Haiti without adoption certificates. The arrests came as aid officials urged a halt to short-cut adoptions in the wake of the earthquake.

Silsby originally said the children were orphans or had been abandoned. But The Associated Press determined that at least 20 were handed over willingly by their parents, who said the Baptists promised to educate their kids in the U.S. and let them visit.

The fact that the children were given up voluntarily helped convince Haitian Judge Bernard Saint-Vil to free the eight without bail on Wednesday.

United Nations appeals for $1.4B

The United Nations said $1.4 billion is needed to provide food, water, shelter and sanitation to 3 million Haitians throughout 2010, the largest appeal following a natural disaster in the world body’s history. The request includes the $577 million initially sought for the first six months after the Jan. 12 earthquake. The U.N. has received $619 million so far from its member nations.
