Yeah, it's important to note that there was no one else with her on that surveillance footage, that she was spotted alone, meaning that she hadn't gone there to meet up with someone, at least as far as we can tell from the video evidence.

So there is no additional person of interest

that investigators can be looking for at this time.

That's why this is so important that this canvas extends to the surrounding residences to find any footage that could potentially have Amy walking by at that time so we can see who else may have been following her, may have been with her earlier prior to this captured footage in the park.

Yeah, there's a couple major roads to the north is Route 13 and to the south 580, which is not far from Diamond Park.

So you're spot on to say that the egress from that area is quite simple and would be fast.

So we have to immediately extend this canvas to the surrounding cameras

be they residential or commercial, in and around Diamond Park around the time she was last seen.

You've got, Nancy, there's a lot of access by roads running in and around the area.

We are dealing with neighborhoods, family homes, but as you see on the map there, there is one road that runs along this path that canvases and connects most of these areas.

As you look, you'll notice that

the park that we started with at Lake Merritt and going to Dynasty, there is that one main road, but look aside all around its residential area.

You've got those huge trees running as you look there.

You've got redwoods all over this area and easy

access out of the park on the road and you're into town.

You're heading into Oakland and San Francisco.

You're in the Bay Area in a matter of minutes, Nancy.

It's not a far off journey from the park into areas of a lot high population.

We're talking 8 to 10 miles.

The search has extended into Oakland neighborhoods and major parks beyond Diamond Park, Nancy.
