LOUISVILLE, Ky. (WHAS11) -- The Highlands has seen an outpouring of grief this week and the community is still on edge.

“It don't make sense,” said Tymna Outlaw. She works on Bardstown Road, not far from where Jason Spencer, 30, was shot and killed on Sunday night when taking an evening walk with his wife.

“This is a nice and good neighborhood to enjoy yourself, it's just sad,” Outlaw explained.

Three 15-year-olds have been arrested for the murder of Jason Spencer. The Commonwealth's Attorney's Office says it's likely all three could be charged as adults.

Highlands resident Margaret Miller told WHAS 11 news the violence may have hit her home, but she worries for all of Louisville.

“It was an isolated issue in the Highlands, but my concern is for the inner city, throughout the city of Louisville, everywhere, times are getting worse.”

Throughout the week, there have been vigils in the Highlands and across town at Christ Church United Methodist where Jason Spencer's wife once worked. There were also peace walks and police have said they are beefing up patrols in the Highlands.

Miller said the tragedy of Sunday is still sinking in.

“It does kind of put a halt to coming out, especially in the evening, and yeah it has swayed us a certain way to be more careful because it could've happened to anyone.”

The Commonwealth’s Attorney’s Office is considering three requirements when it comes to the minors being tried as adults: the child must be at least 14, and he or she is accused of committing a felony, and that it involved a firearm.
