And while that might sound strange given how viciously she was stabbed, it actually might make sense.

Remember, investigators estimated that Milagros was killed sometime between 8.30 a.m.

and 11 a.m.

on a Wednesday.

I think a lot of neighbors were probably at work.

But Detective Holtz also thinks that people may have been hesitant to talk to police in the first place.

Maybe the neighbors in 1993 knew more than they were willing to say.

It's also very possible that every neighbor was being honest and no one heard or saw anything suspicious because there was nothing suspicious to see or hear.

In which case, it would seem far more likely that Milagros knew her killer.

And when examining those closest to her, we discovered a tangled web that wouldn't reveal itself fully until this very year.

Because Edwin Rivera was Milagros' current boyfriend and the one who called 911, he would naturally get increased attention from police.

Thing was, though, Edwin had an easy alibi.

Milagros was seen alive after he left for work, and he was accounted for at work during the time investigators believed Milagros had been killed.

In fact, he was so distraught that he couldn't even stay in town.

He eventually packed up and left Bridgeport before moving back to Puerto Rico.

The family said that he was never quite right after Milagros' murder.

So with investigators pretty confident that they could rule out Edwin, they shifted their attention to other people in Milagros' life.

Who was she close with?

Who had she been close with?

And at the top of their list was Milagros' ex-husband of 12 years, Wilfredo Padilla.
