KILLEEN, Texas (CNN) -- Authorities have identified the man who opened fire at Fort Hood in Texas on Wednesday, killing three people before committing suicide, as Army Spc. Ivan Lopez, an Iraq war veteran.

Sixteen more people were injured Wednesday when he opened fire at Fort Hood, the sprawling Army post in Texas where another mass shooting there left 13 dead in 2009, officials said.

hoodLopez was engaged by military police before he fatally shot himself in the head, said the Army post's commander, Lt. Gen. Mark A. Milley.

The suspect "had behavioral health and mental health" issues, Milley told reporters late Wednesday.

The general said there was no known motive for the shooting.
