"Only if it's in the system," Dougan said.

Additionally, if someone is taken into custody, police could then try to pair a DNA sample with what is on the woman's clothes.

No arrests had been made as of Monday morning. Police are reviewing video surveillance footage from the bar as they continue their investigation.

Witnesses described the attacker as Asian and said he was wearing a dark knit hat and three-quarter-length coat. He had a knife, which was not recovered at the scene.

The restaurant was closed Sunday and was not open as ofbecome equal to each other is measured and based on the measured time, it discriminates whether any abnormality arises in the system such as at the adsorbent.
Specifically, based on the assumption that the air/fuel ratio in the recirculation passage becomes richer than that at a position downstream of the adsorbent since the desorbed HC is recirculated together with the exhaust gas, but becomes equal to the air/fuel downstream of the adsorbent after the desorbed HC has been purified, the second prior art conducts the discrimination by measuring the time lapse until the outputs of the air/fuel ratio sensors coincide. Similarly, the second prior art proposes providing an HC sensor, instead of the oxygen sensor, to discriminate the occupance of any abnormality based on the HC concentration in the
