Soldier Suicide

The suicide of Fort Carson Green Beret William Howell is getting attention from the Defense Department.

DOD researchers are asking for a blood sample from Howell. They are looking for traces of narcotics and an anti-malaria drug called "lariam" which can have psychiatric symptoms.

Howell shot himself in front of his house in Mounment after a confrontation with local police.

He had been home just 3 weeks after serving in Iraq for 10 months.

His suicide raises questions about the use of lariam and the Army's post-combat screening of soldiers.
