The fifteen-year-old boy who lost his mother and younger siblings in a brutal murder this week reportedly fears he will be targeted as authorities work to identify a suspect.

Isaiah Smith’s mother Shanta Myers, 36, and his sibling Jeremiah, 11, and five-year-old Shanise, were found dead along with Myers’ partner Brandi Mells in their Troy, New York, apartment on Tuesday. All four victims had been bound and their throats were slashed.

The Times-Union reports that Isaiah has joined relatives in a public appeal to help find his family’s killers, as authorities believe the victims were targeted.

“I’m scared to go to the corner store,” Isaiah said in a news conference Thursday evening.

“I’m not sure if they’re coming for me next.”

Shakera Symes, Shanta Meyers’ sister, urged anyone with information to come forward.

Give the information to the authorities so that they can help find the person who has destroyed us, emotionally, mentally,” Symes told reporters.

“It feels like somebody has ripped us to shreds.”

The violent crime has put the community along the Hudson River on edge.

“After being in this business for almost 42 years, I can’t describe the savagery of this,” Troy police chief James Tedesco said in a press conference earlier this week.

“There are certainly reasons to be fearful,” Troy Pastor Jackie Robinson Sr. told the Times Union.

“We don’t know who did it. Until we find out, it certainly makes sense to be vigilant and keep your doors locked.”
