A soldier believed to be from Lake County has died in Iraq, the U.S. Department of Defense announced Tuesday.

U.S. Army Pfc. Steven F. Shapiro, 29, died Oct. 21 in an unspecified, non-combat situation, said Tyler Broadway, a spokesman with the Army's III Corps at Fort Hood, Texas, where Shapiro was stationed.

The cause of his death is under investigation, Army officials said.

Family members could not be located Tuesday and high schools near Hidden Valley Lake had no record of Shapiro.

The Department of Defense listed his home town as Hidden Valley Lake but Fort Hood officials listed it as Hidden Valley. There are several towns in California called Hidden Valley.

However, Fort Hood officials also had his home town zip code as 95467, which indicates Hidden Valley Lake.

Shapiro had been assigned to the Texas-based 3rd Battalion, 8th Cavalry Regiment, 3rd Advise and Assist Brigade, 1st Cavalry Division, since July 2010, according to the Fort Hood public affairs office.

He was working in support of Operation New Dawn when he died in Tallil, Iraq, according to the defense department.

Shapiro entered active-duty service in March 2010 as an tank crewman, Army officials said.
