MARINE Seaman Calvin Hanna hid behind an office desk in Government House's guardroom to avoid being shot by another marine who is accused of killing their superior in 2019, a jury heard.

Able Seaman Jevon Seymour is charged with the shooting death of Petty Officer Percival Perpall, along with the attempted murders of Marine Seaman Hanna and Ellis Rahming.

According to police reports, the three officers were attacked while on duty at Government House.

They were said to be in a guardroom when an assailant entered and opened fire on them around 2.30am Sunday, April 28, 2019.

Seymour has maintained his not guilty plea during his trial before Senior Justice Bernard Turner.

When Marine Seaman Hanna took the stand yesterday, he said he was posted to Government House at the time of the incident.

He said after 2am on April 28, he began his patrol by heading east to ensure the eastern gate of the property was locked and secured. After this, he said, he made his way around the western portion of the property before heading upstairs to the guardroom where PO Perpall and Marine Seaman Rahming were.

He said PO Perpall was sitting on a couch that was stationed on the left side of the guardroom. He said after he wrote in the log book, he stood up and conversed with Officer Perpall for about five minutes.

A short time later, Marine Seaman Hanna said he heard the “cocking of a gun” and when he looked through the guardroom’s door, he saw Seymour.
