Chattanooga memorial at military recruiting office grows with

In the four days since Mohammed Abdulazeez shot and killed four marines and fatally wounded a Navy Sailor, the Federal Bureau of Investigation has yet to find a direct link between him and any overseas terrorist group.

He was first treated by a child psychiatrist for depression when he was 12 or 13 years old and several years ago, relatives tried to have him admitted to an in-patient program for drug and alcohol abuse but a health insurer refused to approve the expense.

‘The person who committed this awful crime was not the son we knew and loved, ‘ it added. The windows, several of which were pocked with bullet holes after the shooting, have been covered with plywood.

Abdulazeez was killed in a shootout with police at a Marine-Navy facility.

Investigators continue to search for a motive in last Thursday’s killings carried out by Muhammad Youssef Abdulazeez, and are trying to determine if there is any significance to his presence in a city that is home to both jihadist sympathizers and a USA airbase.

He blended into everyday life in Chattanooga as a clean-cut high school wrestler who graduated from college with an engineering degree and regularly attended a local mosque.

The revelations come from Abdulazeez’s diary, that Ross says is now in the hands of the FBI.

A law enforcement official told the New York Times investigators were looking into a text message Abdulazeez allegedly sent to a friend hours before the shooting to probe possible motives.

In a statement released last Saturday, Abdulazeez’s family expressed grief and sorrow over his actions in Chattanooga.

The family’s explanation fits a pattern of behavior by Abdulazeez that includes a drunken driving arrest earlier this year and the loss of a job over a failed drug test.

ABC said that Abdulazeez was taking sleeping pills to deal with an overnight shift at work, and was considering filing for bankruptcy because he was thousands of dollars in debt.

That arrest was deeply embarrassing for the Chattanooga gunman and sunk him further into depression, according to reports.

The Hixson, Tenn. native, who was arrested this past April 20 in connection with drunk driving, was also facing proceedings in criminal court in the incident.

The family representative told ABC that Abdulazeez “was susceptible to bad influences” and would be affected by watching news accounts of “children being killed in Syria”. He told a Chattanooga officer he was with friends who had been smoking marijuana. Some close relatives learned of the charge only days before the shooting.
