Lara Logan on Marie Colvin

Lara Logan talks about the late journalist Marie Colvin.

The mother of journalist Marie Colvin, who died in a rocket attack in Syria, said her daughter was on the verge of leaving the city because it was so dangerous.

Rosemarie Colvin described her daughter as passionate about her work, even when it got extremely hard.

The 55-year-old Sunday Times reporter died alongside French photographer Remi Ochlik, 28, in a rocket attack on the besieged city of Homs this morning.

Logan believes that Colvin may have been targeted by the Syrian government. Colvin was reporting that the Syrian government was killing civilians with impunity.

For those wondering: Colvin lost her eye covering a war in Sri Lanka.
