GILBERT, Ariz. (AP) - Police in the Phoenix suburb of Gilbert now say they're not sure whether a man who fatally shot four people, including a toddler, committed suicide.
    
Police originally said the gunman killed himself Wednesday, but they now say they're not positive about that.
    
At a briefing for reporters, Gilbert police Sgt. Bill Balafas says all the evidence points to the shooting being a domestic violence situation. He didn't elaborate.
    
Authorities say the man was armed with several firearms, and officers recovered two handguns and a shotgun.
    
The gunman's identity and motives aren't immediately known.
    
Balafas says the genders and ages of the victims aren't known either, except for the toddler, a girl between 1 and 2 years old.
