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. 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!" Custom Nike Detroit Tigers Jerseys .

Everton Preview West Ham manager Sam Allardyce has been around the game long enough to not get too high when things are going well and not get too low when they arent.LOS ANGELES -- Mike Brown had no interest in rehashing his past with the Los Angeles Lakers -- not right now, not with his new team struggling. Hes much more intrigued by the possibilities in the Cleveland Cavaliers future after a breakout game by their newest acquisition. Luol Deng hit five 3-pointers while scoring 27 points, Anderson Varejao added 18 points and 18 rebounds, and the Cavaliers beat the spiraling Lakers 120-118 Tuesday night. Dion Waiters scored 13 of his 17 points in the fourth quarter as the Cavaliers improved to 4-16 on the road. They also won for Brown in his return to Staples Center to face the Lakers, who fired him early last season before descending into the mess of a team that couldnt keep up with Cleveland down the stretch. "I dont care where I am, I really want wins," Brown said. "If we win, I can take some satisfaction from it, but theres a lot of learning we can do from this game, too." Jodie Meeks hit six 3-pointers while scoring a season-high 26 points in injury-plagued Los Angeles fifth straight defeat. Nick Young scored 28 points, but the Lakers have lost 11 of 12 heading into a punishing seven-game road trip starting Wednesday in Phoenix. "This is hard," said Young, who missed a potential tying 3-pointer with 10 seconds left. "Were losing, and were losing players daily. Its frustrating, but weve still got to get up and play basketball. Nobody wants to get embarrassed. Youve got to still take pride in that Lakers uniform." Brown coached just 71 games with the Lakers, who hired him to succeed 11-time NBA champion Phil Jackson in 2011 and then pulled the plug on his tenure five games into last season. Brown expressed no hard feelings or regret about his brief tenure with the Lakers, saying hes still on good terms with Kobe Bryant and other Los Angeles players. Deng had five rebounds and four assists his first big game since joining Cleveland in a trade with Chicago a week ago. He was the centerpiece of the highest-scoring regulation performance of the season by the Cavs, who hit 13 of 17 3-pointers and outrebounded Los Angeless 48-35 to earn their second win in three stops on a five-game trip.dddddddddddd "Theres a lot more optimism and a lot more talent now that Luol has been added to the mix," said Kyrie Irving, who had 13 points. "Hes a great addition, and to get him on this road trip was big for us." Deng and Waiters put the Cavs ahead during a 12-0 rally early in the fourth quarter, but Young hit three free throws with 25.3 seconds to play, trimming the lead to two points. Tristan Thompson missed two of four free throws in the final 16 seconds, but Young missed two late 3-pointers. "We talked at halftime about coming out with a lot of energy, and I thought we responded well," Deng said. "Once we got the lead, they tried to get back in the game, and it was back and forth. But I thought we did a good job of keeping the lead and controlling the game at the end." Pau Gasol had 20 points and 12 rebounds in the Lakers only home game in a 22-day span. Los Angeles will be away for the next two weeks while the Grammys take over Staples Center. Kendall Marshall had 10 points and 16 assists for Los Angeles, which had just nine players in uniform. Bryant, Steve Nash, Steve Blake, Jordan Farmar and Xavier Henry are all out with long-term injuries, and Gasol only determined he could play on his injured big toe after pregame warmups. "It wasnt like our energy and focus werent there," Gasol said. "We hung in there, but we couldnt pull it off. ... The defence needs to improve drastically, thats for sure. Whatever it takes to secure those boards, we need to be there." NOTES: Henry wont return from the bone bruise in his right knee for at least another week, but hes likely to be the first injured player back for Los Angeles. ... Nash wont travel on the Lakers upcoming road trip, instead heading back to Vancouver for rehab on his assorted injuries. The two-time MVP hasnt played since Nov. 10. ... F Earl Clark, who parlayed a decent season with the Lakers into a free-agent contract with Cleveland last summer, scored two points in five minutes. ' ' '
