Less than a week after Kayla Hamilton turned 20, she was violently killed by an illegal alien MS-13 gang member in her bedroom, her mother told a House subcommittee Tuesday.

The suspect in Hamilton’s slaying is a 17-year-old unaccompanied alien child affiliated with MS-13 in El Salvador, according to Tammy Nobles, Hamilton’s mother.

“I don’t want any other parent to live the nightmare that I am living,” Nobles told during a House Judiciary subcommittee hearing.
