NORCROSS, Ga. -- Authorities are investigating a possible link between a fatal triple shooting in Norcross and an Atlanta homicide.
Around 4 p.m. Friday, police were called to a house on Pebble Creek Drive in Norcross by a father who said he arrived and his wife, adult son and his 10-year-old daughter dead.
Shortly before that, police in Atlanta found 40-year-old Quincy King shot to death in an apartment complex on Northside Circle.
On Monday, police identified those killed in Norcross shooting as 55-year-old Josephine Roby-Skinner, 10-year-old Jasmyn Skinner and 26-year-old Jermaine Roby. According to the police report, Jermaine Roby called his father, Vernon Skinner Friday afternoon and told him to come back because Jasmyn was sick. When Skinner got home, he found all three family members lying in in a pool of blood.

Authorities believe that Jermaine Roby may have shot his mother and sister before turning the gun on himself.
Police are now investigating the possibility that Jermaine Roby may have been connected to the shooting of King.
The Atlanta Police Department released a statement late Monday morning saying they are working with Gwinnett County detectives to compare ballistic evidence and determine how the the two may have known each other.
