Police in Jamaica say that one of the men charged with killing two American missionaries has escaped custody.

Dwight Henry is accused of murdering Randy Hentzel and Harold Nichols during a robbery in St. Mary’s Parish Jamaica. The two American missionaries were found dead on April 30, 2016. They had lived in the parish for years. Andre Thomas is also charged with the crime.

Jamaica Constabulary Force Superintendent Stephanie Lindsay told Crimesider that Henry apparently became ill Wednesday afternoon and was transported to the hospital, where he was able to escape his police guard.

Lindsay said officials do not believe Henry has left the island, and they are currently searching for him and investigating the circumstances of the escape.

“There are a lot of citizens in St. Mary’s who are very angry about this crime,” said Lindsay, and authorities are concerned about Henry’s safety if he is captured by someone other than the police.

Hentzel and Nichols both worked for a Pennsylvania-based religious organization called Teams for Medical Missions.
