"At a press conference later on Monday, Ammar said he was 'really confused' by the prosecutor's decision to drop the case.'I'm very sad, very upset. This is very unfair.'
"Ammar's lawyer said police had failed to find the knife in a search of the cab after the incident, but his client uncovered it several weeks later beneath the carpet on the front passenger side of the car.
"Yes, certainly the police would have neglected to lift up the carpet.
"Ammar told prosecutors in May he had found the knife, said the lawyer, Hassan Ahmad, who conceded the delay was a mistake but said the driver was scared to reveal his discovery because he had touched the knife and left fingerprints on it.
"That would not, in reality, be a problem, unless Jennings' fingerprints were not also on the knife, which at this point seems likely."
