No he was not. He was watching him. Wanted to make sure he could tell police where he was last seen. TM had already disappeared from his sight.
People on the hunt to kill someone don't call police and invite them to the crime scene. They kill and cover up. This guy did not intend on hurting anyone.
people on the hunt to kill someone are exactly the kind of people who call for help and then ignore the advice.
GZ refused to even provide his location to NEN, insisting instead that cops call him when they arrived. do people really doubt that GZ knew that neighborhood like the back of his hand? i find that astonishing. far more likely and rational, imo, is the notion that he did not provide a location because he had every intention of continuing to hunt down TM all along.
regarding injuries to GZ's head. let's not forget that he refused to go to the hospital. had he reported to emts that his head had been slammed repeatedly on the concrete, had he shown even an inkling of a sign of head trauma, he would not have had a choice. emts would have taken him to the nearest er immediately. it is to the defense's benefit to exaggerate his injuries. it is to our benefit to remember this.
TM had no DNA on his hands. no blood. no nothing. GZ did. both were in the same elements. i do not find it believable for an instant to think that the rain could have washed all evidence of GZ off of TM and not vice versa. in fact, the opposite would be more believable considering that TM collapsed dead with his hands underneath his body, protected from the rain. GZ, on the other hand, was alive. he had time to walk around and wring his hands and who knows what else.
to date, there has been much speculation, little fact. personally, i believe that as this trial progresses, GZ is going to think back on that 16 months of speculation and consider them the good ole days.
