At 12:50 pm, I was at the command post.

I get a call from Lieutenant Clarence Shelley to "mobilize" the team, before heading to Columbine.

The SWAT team, at the time, had already started entry into the school.

I get there and had to park at Leawood Elementary due to the traffic.

I was told to only talk to the police officers that had been there, sooner than me.

While I was at Leawood Elementary, my colleagues were handing me possible evidence from Columbine to Leawood.

For a double check, real quick to see if it was safe.

I ended up, getting four firearms in my hands before handing the evidence to criminalist, Vicky Spelman who was with me.

I made my way, back to the command post at that point.
