Police may close the case of two friends murdered in Georgia. Their families are furious.

Nearly 10 months after two close friends and a neighbor were fatally shot days apart in Georgia, authorities have offered the public few answers about their deaths. But a relative of one of the victims said police have identified the possible killer and are planning to close the case in a decision that has left her “heartbroken” and “frustrated.”

Therasa Johnson’s younger sister Ronisha “Nikki” Anderson was one of the friends gunned down on March 7 outside the home office where the victims worked in Columbus, Georgia.

Two days after the women were killed, Adams, 65, a convicted sex offender who served more than a decade in a Florida prison before his release in 2007, was found dead in his bedroom, a coroner’s death report shows.

Adams’ house — the second to last on a dead-end residential street southeast of downtown Columbus — was next to the home where Anderson lived and worked.

Johnson said the detective told her a witness who heard the gunfire looked out her window and saw Adams in the home’s front yard at the time of the killings. His hands were…
