It's official—it looks like a serial killer is stalking a suburb of the nation's capital.
Police have just confirmed what many fearful residents have long suspected about three mysterious murders in Alexandria, Virginia.
Police Chief Earl Cook said at a press conference, "The cases appear to be linked."
And cops are now spelling out a grim warning, informing people at a press conference, "If any of you are suspicious of anything, please don't open your door. Call the police."
Last month INSIDE EDITION reported how the slayings had many residents living in fear.
- All three victims were shot after answering their front doors.
- All were prominent citizens.
- All the slayings took place in broad daylight.
Police are now revealing that the markings on the bullets show the same gun may have been used in all three murders.
Cook said, "The bullets have the same general rifling class and characteristics and are similar in design for all cases."
The suspect being linked to all three murders is middled aged and balding.
Criminal profiler Pat Brown believes the serial killer has a chip on his shoulder against authority figures.
INSIDE EDITION's Paul Boyd asked Brown, "What's your best guess at who this individual might be in terms of his psychological makeup?"
Brown replied, "It seems to be like somebody who's angry. This is the kind of person who writes in to newspapers to say how angry it is, with all the kinds of different things that are happening in the government. I believe we have a person who is psychotic, who has mental problems, who then is getting enraged and thinks he's going to go out and take care of the world."
The most recent victim, 59-year-old music teacher Ruthanne Lodato, was shot dead in the doorway of her home in February.
Three months before Ruthanne was gunned down, 69-year-old Ron Kirby, a high-ranking official in a Washington D.C. transportation agency, was shot dead in his home about a mile away.
His heartbroken widow, Anne Haynes told INSIDE EDITION's Paul Boyd her husband most likely went to the door without hesitation because he was expecting the plumber.
"Nothing was stolen?" asked Boyd.
"No. His wallet was upstairs on the desk with money in it. Our computer was there. They didn't take anything. I think they just turned around and left," replied Haynes.
The third victim was 56-year-old realtor Nancy Dunning, the wife of the Alexandria sheriff. She was shot in her home 10 years ago.
Boyd asked Brown, "This is a good old fashioned manhunt, isn't it?"
"He is armed. He is dangerous, and he's will to take the chance of simply going up to the door and knocking and shooting somebody. He may not have a lot of love for his own life at this particular point in time. So, I do beleive that they need to catch him and they need to catch him soon," said Brown.
