17-year-old charged after shooting 19-year-old woman to death at Crosby home, deputies say

CROSBY, Texas (KTRK) -- A 19-year-old Houston Christian University student was shot and killed while taking down Christmas decorations in her home in Crosby, the Harris County Sheriff's Office said.

It happened around 9 p.m. Thursday in the 4400 block of Sherri Lane near Lord Road off Highway 90, deputies said.

The woman, who was later identified as Marissa Dikeman, was with two 17-year-olds who were her coworkers. Her grandfather told ABC13 that Dikeman had gotten off work at about 7:30 p.m. and went home to take down Christmas decorations with her coworkers who were also her friends.

One of those teenagers, Cayman Wilson, has now been charged with manslaughter, documents say.

Further investigation revealed the boys were helping Dikeman take down Christmas decorations when Wilson pointed and fired a shotgun at the 19-year-old.

"My understanding is that firearm may belong to the victim's roommates who were not present at the time of the shooting," Sgt. Greg Pinkins said.

Wilson was booked in the Harris County Jail. The other 17-year-old boy has not been charged.

Dikeman's grandparents said they know Wilson and knew him to be "a good kid," and don't want him to be charged.

"It's bad enough that he has to live with what happened the rest of his life," Dikeman's grandfather told ABC13.

While a student at Crosby High School, Dikeman was an award-winning member of the 4H club for raising steer, turkeys, and chickens. Fast forward to college, her mother says she was studying educational administration and would have graduated from Houston Christian University in 2023.

Her grandparents tell us she worked at the family's deer processing company less than a mile down the road. She was the youngest of three siblings.
