Police are investigating and say there is a strong likelihood that a serial killer murdered three men over the past 11 years in a southwest Atlanta neighborhood.

Atlanta police homicide Detective Vincent Velazquez spoke about the investigation Thursday.

Authorities also see a potential connection to a fourth victim.

Velazquez said there is a person of interest who is very comfortable in the neighborhood but would not release further details.

The first victim was 56-year-old Alfred Glass, a self-employed contractor who was shot to death in August 1998, as he worked in his garage.

Police have connected two other subsequent murders - those of Dennis McGuire in 2007 and Warren Williams Jr. in 2008 - with the
same gun.

Velazquez said a fourth victim, Joseph Williamson, may also have been murdered by the same person in 2007.
