MARTHA RADDATZ, ABC HOST: Good morning.

I'm Martha Raddatz.

Hope you had a great Thanksgiving.

We'll get to the 2016 race shortly, including Ben Carson standing by in Jordan, revealing what he's learned on that surprise trip to the refugee camp there.

But we start off in Colorado -- brand new details on the investigation into that deadly shootout at Planned Parenthood, revelations the shooter may have been targeting the group. Our exclusive interview with a top Planned Parenthood official momentarily.

First, ABC's Clayton Sandell on the ground with the latest -- good morning, Clayton.

CLAYTON SANDELL, ABC NEWS CORRESPONDENT: Good morning, Martha.

Investigators here are trying to piece together the facts here this morning, but also trying to get inside the mind of an alleged killer.

(BEGIN VIDEOTAPE)

SANDELL (voice-over): This morning. Law enforcement sources are not officially saying why they think Robert Dear allegedly launched a five hour attack.

UNIDENTIFIED FEMALE: (INAUDIBLE) is working an active shooter.

SANDELL: But they do say after his surrender and arrest in Colorado Springs, he allegedly made rambling hostile statements about his target, Planned Parenthood.

UNIDENTIFIED MALE: We're pinned down -- we're getting active gunfire.

SANDELL: On Saturday, police and federal agents showed up to his remote trailer home in Hartsel, Colorado, 90 minutes away, where neighbors say Dear kept to himself, but always seemed a little off.

UNIDENTIFIED MALE: We got some anti-Obama pamphlets. So that was just kind of weird, just like three minutes of meeting somebody and they're already wanting to give you that kind of stuff.

SANDELL: U.S. Attorney General Loretta Lynch calls the shooting a crime against women receiving health care at Planned Parenthood. The organization itself says the gunman was motivated by opposition to safe and legal abortion.

UNIDENTIFIED MALE: It happened at a Planned Parenthood Center.

SANDELL (on camera): What does that tell you?

UNIDENTIFIED MALE: My -- my suspicions are is that this -- that has a lot to do with the motive.

SANDELL (voice-over): But knowing the motive won't brig back three victims, one a 44-year-old University of Colorado police officer, Garrett Swasey, a married father of two, once a champion junior ice skater.

UNIDENTIFIED MALE: And he wanted to be in the Olympics and he wanted to make a mark.

SANDELL: The two other people killed still haven't been officially identified. Nine more were wounded, but expected to be OK.

Others just feeling lucky.

UNIDENTIFIED MALE: When I saw myself in the mirror and it's like, my god, he was aiming for my head.
