Roughly six hours after a civilian worker was gunned down at Fort Knox, Kentucky, this quiet Portland neighborhood became the focus in the search for the man responsible."They came to my house at 11:30," Bob Morris said.Morris could only watch from his windows as officers and agents surrounded his home late Wednesday night."They were staged behind my shed over here. They were leaning on my car in a defensive position, I guess," he explained.The Morris family was one of the last to evacuate. His neighbor Kathy Sharlow was one of the first at 2 a.m."He said, 'We need to evacuate.' And I said, 'What's going on?' And he said, 'There's been a murder'," Sharlow said.The murder happened 116 miles away at Fort Knox. According to a federal criminal complaint, a civilian worker in charge of handling personnel actions of soldiers was shot and killed in a parking lot on post. A witness and shell casings linked 36-year-old Marquinta Jacobs to the murder. Jacobs, a soldier, was believed to be held up here, in his mother's Portland home.Neither Sharlow nor Morris recognized him."The person they showed me, it looked in his picture, maybe early 30s or somewhere like that. The person I'm used to seeing is at least in his 50's," Morris added.And Sharlow said, "I would see a younger guy there, possibly a son. But he did not look like the suspect that we saw earlier today."Jacobs was apprehended away from the neighborhood hours later.A relief to those in this neighborhood that is quiet once more. "They caught him earlier today, so we can sleep tonight," Sharlow expressed.
