Parker said the case was under investigation, but he was able to give some details surrounding the death.
Parker said that Tyler police were contacted about a missing person who had not been seen by his family for several days.
Records show that Powell’s family reported him missing on Monday morning and the report states he had not reported to work on Friday and had not been seen since leaving home Friday.
Parker said the missing man’s pickup and boat trailer were found at a marina at Lake Palestine on the Smith County side of the lake on Monday and game wardens were dispatched to see if the man possibly capsized his boat or had some other type of trouble.
Parker said upon the discovery of the body on the island, game wardens called his agency for the incident to be investigated.
Henderson County Justice of the Peace Sue Starnes was called to the location for an inquest and she sent the body to Southwest Institute of Forensic Sciences.
On Tuesday Judge Starnes received the preliminary autopsy report indicating the manner of death was a self-inflicted gunshot wound to the chest.
According to Moore’s school website, Powell had been at Moore for 13 years and had taught at both Boulter and Dogan middle schools as well as in Louisiana.
“We’re just devastated and cannot believe this has happened,” one friend of Powell’s said Tuesday.
TISD Director of Guidance and Counseling Marty Barbieri said counselors were on campus at Moore all day to help students and staff deal with the death.
“Students and staff are hurting as this was a long time employee of the district who was loved,” she said.
Ms. Barbieri said Powell’s students were allowed to gather in the gym and talk about his death.
“We told them to grieve the loss and not to focus on the questions about how he died,” she said.
Ms. Barbieri said the students were allowed to put posters on the walls of the school as a memorial to Powell.
“I can tell you that it is a difficult day at Moore,” she said.
