Police are studying footage from shop security cameras
in the hunt for missing special needs teacher Jane Longhurst.
The Brighton and Hove Bus and Coach Company is also providing CCTV tapes from buses.
Detectives yesterday trawled through hours of film in the hope of spotting Miss Longhurst on the day she disappeared.
It is two weeks ago today that Miss Longhurst, 31, vanished from her home in Shaftesbury Road, Brighton.
Despite hundreds of inquiries, police still have no idea of her whereabouts. They fear she may have been abducted.
Police revealed the last person to see her may have been a schoolgirl who "skipped" round Miss Longhurst as she walked to her front door.
A neighbour saw the teacher at 2.40pm on the day she disappeared, walking home carrying two shopping bags.
The neighbour told police a girl of about 12 and what appeared to be her mother, were close by on the pavement at the time.
Chief Inspector Steve Dennis said: "The girl apparently skipped round as Jane climbed steps to her front door.
She and the woman may have seen something that could provide us with vital clues."
The girl is about 5ft 2in with dark hair. She wore a pink dress or skirt and top. The woman is about 5ft 5in with dark hair. She wore dark clothing.
Mr Dennis appealed to the two and anyone with information, to call the Operation Keen incident room on 0845 6070999.
