JACKSONVILLE, Fla. -

Neighbors in Murray Hill were on edge Friday night after four people were killed late Thursday night.

Margaret Boswell lives in the neighborhood where the four people were shot.

"I go in and lock my doors and it's a shame. I go in my house and sit and not feel safe," said Boswell. "I just can't do it. You just can't do it in this neighborhood anymore."

Crime scene tape has pierced the Murray Hill neighborhood and longtime residents like Margaret and Scott Boswell told Channel 4 that they go to sleep at night, uneasy.

"They're still out here, they're still here, and how long is it gonna take to find them?" said Boswell. "You don't know, you don't know how long it's gonna take. You don't know what the circumstances were, they have no clue who did this."

"It concerns me that there is a killer on the loose," said neighbor Denise Flowers, "but I know it is in the hands of God, so I'm not going to worry too much."

The murders on Randolph Street have brought feelings of security to a dead-end in the neighborhood. Neighbors said they are fearful because whoever killed Keshell Brown, Keyonna Brown, Gontrell Hagans and Derek Williams is still out on the streets.

Deidre Eade is a single mother with three small children. She's now wondering if she'll wake up to more police sirens in her neighborhood.

"I don't think I will be living here another year," said Eade.

Police are asking anyone with any information on this case to contact Crime Stoppers 1-866-845-TIPS.
