Dylan Redwine

John Grusing, a crackerjack detective, has been an integral force in investigating numerous Colorado murder cases.

That includes the case of Dylan Redwine, whose bones were also found after years of going missing.

Grusing has continued to advise on the case sources close to the investigation have told the Denver Gazette.

None of this is good for Barry Morphew, by the way.

Years later, that father was convicted of his heinous murder.

Maura Murray, Ellen Greenberg, Dylan Redwine, three cases that crawl deep into your brain and stay there.

We begin on a stretch of winding, snow-covered road surrounded by trees, where more than 20 years later, nursing student Maura Murray was last seen.

When Maura first vanished, nobody could agree on what kind of story they were dealing with.

In our next troubling case, one parent was definitely the opposite of that.

He was the killer.

13-year-old Dylan Redwine went to a court-ordered visit with his father in Colorado, but he never came home.

While Dylan was still missing, I sat across from his father, Mark Redwine, and asked him directly if he had harmed his youngest son.
