OSHKOSH - Authorities are still piecing together a string of events that led to the shooting deaths of two people on Highway 41.
We're learning more about the people who died, who were in their late 20s. And about how everything started Wednesday with a robbery at a liquor store.
A better view of the timeline of events emerged Thursday about what led to the double suicide.
It started with a robbery a few miles away at Hank's Payne's Point Liquor Store on County Highway A.
A Winnebago County sheriff's deputy spotted the suspects' vehicle minutes later on County Highway GG.
After a short pursuit the suspects pulled over on Highway 41 near County Highway Y where the standoff ensued.
Joann Brescia was the clerk working behind the counter at Payne's Point Liquor Store in Vinland when 29-year-old Randy Lamb came in just before 4 o’clock Wednesday. Brescia says Lamb asked for $20 lottery tickets and she immediately thought something didn't seem right.
"And he proceeded to ask for 10 of them which is kind of strange because we don't have those kind of customers normally,” said Brescia.
Brescia said Lamb acted normally, but then left the store.
"He said he had to go out to his car to get his wallet," she said.
In the meantime, Brescia called for a co-worker to come into the liquor store to observe from the back of the room when Lamb came back in.
"And he had a gun and he said I need all of the money out of your register,” said Brescia.
When a sheriff's deputy pulled the vehicle over on Highway 41, a nearly two hour standoff ensued. Deputies, SWAT teams and crisis negotiators pleaded with pair to surrender.
"We were able to do brief negotiations with them, at which time they made outwardly suicidal comments to our negotiators,” said Capt. David Mack, Winnebago Co. Sheriff’s Department.
Shortly after 6 p.m., deputies on the scene reported two shots were fired inside the car.
Ambulances rushed to the scene. Lamb and 28-year-old Ashley Luka were pronounced dead.
The sheriff's department said Thursday both were also considered suspects in burglary where jewelry was stolen from a home in the town of Vinland Tuesday.
Authorities confirm the vehicle did not belong to Lamb. Investigators also said while Luka was not a suspect in the liquor store robbery, she was a willing participant.
No shots were fired by officers during the standoff.
The Oshkosh Police Department is investigating the incident.
Autopsies on Lamb and Luka were performed Thursday. The report says both died from self-inflicted gunshot wounds.
Toxicology results won't be known for several weeks.
The response and investigation caused lengthy backups for some area drivers.
