Did the the killer have a split personality?

[PRIVATE INVESTIGATOR 1]

Mortimer claimed to have seen a man carrying a black bag. The police found him, his name was Leon Goldstein.

That was, I believe, shortly before 1 a.m.

The issue raised by Michael Richards, and to which I responded, is that Mortimer did not see Schwartz at about 12.45 a.m.

My response to that, that no-one saw Mortimer (at about 12.45 a.m.), still stands.

For both Schwartz and Mortimer, we're talking about 12:45, an approximation. Maybe Schwartz passed through just before 12:45 and Mortimer came to her door just after 12:45, and that's why she didn't see him.

Fascinating as they are, posts 12-15 seem off topic to me.

... which is why he could not have been the assailant of Stride seen by Schwartz.

I agree.
