Police blocks from Sigg home after lake attack

WESTMINSTER, Colo. -  

When a jogger reported nearly being abducted on Memorial Day in Westminster, police searched the neighborhood where Austin Sigg lived.

Sigg is in custody, suspected of the abduction and murder of 10-year-old Jessica Ridgeway. Investigators confirm with CALL7 Investigators that they have evidence linking the Ridgeway case with the Memorial Day near abduction at Ketner Lake.

7NEWS reviewed police radio traffic from Memorial Day. It reveals how close police were to Sigg throughout the search.

The first reference to an attack was broadcast at 1:25 p.m.

"He put a rag over her mouth and then hit her," said the dispatcher. "She's still on the north side of the lake. She said the rag smelled like Chloroform."

At 1:27 p.m., officers were directed to meet the victim at the pedestrian crossing light off Countryside Drive near Moore Street.

"Serge, you want to start setting up a perimeter?" asked one officer on police radio traffic.

"We'll need one car at (Wayne Carle) Middle School; 100th (Avenue) and Countryside (Drive). One more at fire station number 5 (Garland Street near 100th Circle) … And then one more to the west," said the sergeant. "We need to see if we got a K-9 available … See if we can set up this perimeter and make him hunker down."

At 1:32 p.m., the description of the suspect was broadcast, along with his last known location.

"Party was last seen southbound on the path at Ketner Reservoir from the traffic light on Countryside (Drive). (He's) described as a while male, brown hair, mid-twenties, wearing a blue baseball hat, sunglasses, blue jeans," said the dispatcher.

At 1:33 p.m., officers determined a firm western perimeter.

"Given the time that's lapsed, could you move the western boundary to Oak Street, about 103rd (Avenue)," said the sergeant.

Sigg's home near 102nd Avenue and Moore Street was within that perimeter. Using the path, his home is a quarter of a mile away from where the victim waited for police. His home was within a half mile of the western search boundary.

Police have not identified what evidence exists that links the Ketner Lake attack with the Ridgeway abduction and murder.
