A 23 year-old Bacliff man is in jail on manslaughter charges after he accidentally shot and killed his 18-year-old girlfriend, Galveston County Sheriff Department investigators report.

The victim, identified as Kaitlyn Trammell of Galveston, was reportedly shot Sunday night around 6:30 p.m. She was taken to Memorial Hermann Hospital in Houston where she was pronounced dead on Tuesday.

According to Galveston County Sheriff's Office spokesman Maj. Douglas Hudson, the victim was watching a movie with her boyfriend, Orlando Martinez, at his home in the 4700 block of 6th Street in Bacliff Sunday evening at the time of the accident.

"A scene came on the movie that showed a gun and Martinez reportedly said 'Oh, I have a gun' and proceeded to take out the gun and show a Smith and Wesson 9-mm gun to the victim," Hudson said. "Martinez removed the clip from the gun, not realizing there was still a live round in the chamber."

The firearm was accidentally discharged and Trammell suffered a single gunshot wound to the head, Hudson said.

The brother and a friend of the defendant were present at the time of the shooting but were in another part of the house. After the accident, a witness reported seeing two men running from the home. Investigators later located and questioned the two men and eventually filed charges against 23 year-old Jared Koehler from Sante Fe for tampering with evidence, after he reportedly confessed that he removed the gun and other items from the scene.

Based on information provided by Koehler, divers from the Galveston County Sheriff's Department were able to retrieve the gun believed to have been used in the shooting from a creek in the Sante Fe area on Wednesday.

Martinez was arrested by Galveston County Sheriff Deputies on Wednesday, Aug. 2 and remains in custody on an $80,000 bond. Koehler is also being held at the Galveston County Jail on a $25,000 bond.

Investigators say the accident remains under investigation.
