- Gas station video shows unidentified person walking in the early morning hours of October 4
- The gas station is less than two miles from the home where Lisa Irwin was last seen
- Authorities decline to comment on the video, citing the ongoing investigation
- Lisa's parents attend an emotional prayer vigil for the girl
Friends and family gathered Sunday for an emotional prayer vigil for a missing 11-month-old Missouri girl as new surveillance video surfaced from the night Lisa Irwin disappeared.
The video, taken from a BP gas station less than two miles from the home where Lisa was last seen, shows an unidentified person walking along the road around 2:15 a.m. October 4.
The station manager, Anuj Arora, said it's unusual to see anyone walking at that time of night in the region.
Arora, who shared the video with CNN on Sunday, said he also turned it over to authorities investigating Lisa's disappearance in hopes it will help in the search for the girl.
The FBI and Kansas City police declined to comment on the video, citing the ongoing investigation.
Meanwhile Sunday, Lisa's parents, Deborah Bradley and Jeremy Irwin, were seen wiping away tears at the candlelight vigil outside their home. They wore T-shirts emblazoned with Lisa's image.
Lisa was reported missing at 4 a.m. October 4, after Jeremy Irwin came home from work to find the door unlocked, the lights on and a window that had been tampered with. Bradley said she last saw Lisa at 6:40 p.m. the night before.
A cadaver dog searching the family's home indicated a positive "hit" for the scent of a body, according to documents released Friday. The information was included in an affidavit, dated Tuesday, police filed to request a search warrant of the home. The warrant was executed Wednesday.
"The cadaver dog indicated a positive 'hit' for the scent of a deceased human in the area of the floor of Bradley's bedroom near the bed," the affidavit read.
It also said that interviews with people involved in the case "revealed conflicting information" and that Bradley told police she did not initially look for her baby behind the house because she "was afraid of what she might find."
The attorney for Lisa's parents said the release of the affidavit Friday was "unfortunate," as it could derail the search for the missing girl.
Joe Tacopina described his clients as "very shaken up and they refuse to believe anything except that she is out there and alive." He said Lisa's parents are "terrified, not for themselves, but for the welfare of their daughter."
Bradley said in an NBC interview last week that she was drunk the night the infant disappeared and that she had last seen the baby about four hours earlier than initially reported.
Bradley told NBC she is afraid she will be arrested. Police have accused her of killing Lisa, she said, and told her that she failed a lie detector test.
"I was the last one with her," a tearful Bradley said. "And from judging on how the questioning went, that's kind of a fear that I have. And the main fear with that is, if they arrest me, people are going to stop looking for her. And then I'll never see her again, and I'll never know what happened."
Asked whether he had questions about Bradley, Jeremy Irwin told NBC, "No. There's no question to be had there. I know who she is. I know the kind of mother she is."
Irwin said it's possible someone could have entered the house without Bradley hearing, as the couple's bedroom is on the opposite corner of the house from Lisa's room and Bradley sleeps with a fan at high speed.
Lisa is described as being 30 inches tall with blue eyes and blonde hair, according to police. She weighs between 26 and 30 pounds and was last seen wearing purple shorts and a purple shirt with white kittens on it.
The missing girl has two bottom teeth and a "beauty mark" on her right outer thigh, police said. At the time of her disappearance, she had a cold with a cough.
