PRETORIA, South Africa -- An expert witness for the defence at the murder trial of Oscar Pistorius was supposed to help the athletes assertion that he killed his girlfriend by mistake last year, but he ended his testimony on Thursday amid blistering attacks on his credibility by a prosecutor who accused him of slipshod analysis and fuzzy explanations. Edrice Adebayo Jersey . Roger Dixon, a former forensic scientist for the South African police, was frequently on the back foot as he tried to fend off sharp questions from chief prosecutor Gerrie Nel, who says Pistorius is lying and fatally shot Steenkamp on purpose after a nighttime argument in his home. For nearly a week, the double-amputee runner was subjected to the same kind of harsh scrutiny when he testified that fear led him to fire four shots through a toilet door at what he thought was an intruder. Legal analysts say Judge Thokozile Masipa will review the mass of testimony in its totality, which is said to be almost 2,000 pages so far, and that it can be misleading to assess the course of the trial by a single witness. Defence lawyer Barry Roux, for example, hounded police witnesses with questions about alleged mishandling of evidence at the house where Pistorius killed Steenkamp in the early hours of Feb. 14, 2013. Masipa, who will deliver a verdict on the premeditated murder charge against Pistorius, adjourned the trial until May 5. Dixon, now a geologist at the University of Pretoria, was forced to acknowledge Wednesday that he had no expertise in light and sound measurement, as well as pathology and ballistics, despite his commenting on those topics while testifying about the circumstances of Steenkamps death. On Thursday, Nel resumed his attack, criticizing Dixons work after the geologist did not use Pistorius exact height when standing on his stumps. The prosecutor questioned why his measurements were 20 centimetres (eight inches) shorter in a test to see if Pistorius head and body would have been high enough to be seen by a neighbour through a window of his bathroom. "It is something I omitted. I overlooked it at the time," Dixon said, adding that he was not trying to "mislead" the court. Nel also questioned Dixons statement that he conducted tests showing that Pistorius bedroom is very dark at night and with the curtains closed, a conclusion that would support the athletes contention that his inability to see his girlfriend on the night that he killed her contributed to the shooting. Nel noted that Dixon judged how dark it was without using any light-measuring equipment. "What one can see using your eyes is a very subjective thing," Nel said. "I wanted to see what I could see," Dixon replied. "A measurement doesnt translate to me into what Im actually seeing." Nel also said Dixon was giving convoluted responses, addressing the judge: "My lady, may I just ask the witness which question hes answering at the moment?" Another time, Dixon picked up a prosthetic leg of Pistorius that had been included as trial evidence while discussing varnish traces that he said were found on the prosthesis and he matched to the door varnish. The defence has cited that as proof that the Paralympic champion tried to kick down the door to get to Steenkamp after realizing, according to his version, he had shot her by mistake. Then the prosecutor chided Dixon for not bringing the varnish sample to court. Dixon appeared serene throughout the rough-and-tumble of his cross-examination. Asked if he knew the states case and other trial details, he said: "I am not like most people. I do not have a television set. I do not have a radio at home." His Twitter handle reads: "I am a mineralogist and forensic scientist, I grow clivias and other plants, have a landrover and a Trans Am. I live in a forest I planted myself." He acknowledged the pressure from the feisty prosecutor in a message on his Facebook account that was apparently posted on Thursday morning. He confirmed its authenticity when questioned by journalists. It read: "Third day in court today. Lets see how much of my credibility, integrity and professional reputation is destroyed. It is difficult to get belief in those who will not listen because it is not what they want to hear. After that, beer!"

Speaking to reporters on Wednesday morning, general manager Bryan Murray said he will have a discussion with the 19-year-old Lazar in the coming weeks, and will then make a determination on the best course of action. Before I would do anything, I would talk to him and see his desire and then wed talk to the coaches. But yeah, Im open-minded. I have a great deal of respect for that junior tournament and how it helps kids, Murray said on Wednesday morning. The Senators would have to make a decision on Lazars status before the Dec. 19 NHL holiday roster freeze at 11:59pm ET. Murray said it was more likely that he would loan out his star prospect for the tournament games and not the training camp that starts on Dec. 11 in Toronto. We will get into December and make a decision. I dont think Ill let him go for the whole training camp, but certainly the tournament would be a consideration. The conversation will take place with Curtis first and if he has a great desire, well certainly consider it, Murray added. Lazar played a key role on Team Canadas World Junior squad that finished in fourth place last year. As an 18-year-old, hhe collected three goals and four assists in seven games and was one of Canadas most consistent forwards. Kelly Olynyk Heat Jersey. Murray says that if Lazar suits up at the tournament again, Hockey Canada executives have assured him he would play a major role on the team. They tell me that if he goes, he could be their captain or certainly be one of their leaders,” Murray said. “And he has that personality that he would be that. He would be a very important player on their team and maybe thats the boost that would really shoot him into the second half.” Lazar could use a boost - at least offensively. He has yet to score a goal in his first 17 NHL games, but has managed six assists and has been a solid performer at both ends of the ice. Murray says its a matter of when - not if - the pucks start finding the back of the net for Lazar, who scored 41 goals in 58 games in his final season of junior hockey with the Edmonton Oil Kings last year. Curtis Lazar is an NHL player. Hes had a struggle getting points or scoring, but again, his work ethic is second to none, Murray explained. Hes real honest guy who knows how to play the game. I just gotta feel theres a breakthrough somewhere here that hes going to get a chance to get a goal and they will come a little easier for him. ' ' '
