PRETORIA, South Africa -- Oscar Pistorius lawyers tried to roll back the prosecutions momentum at his murder trial Wednesday following the star athletes shaky testimony, presenting a forensic expert who quickly found his own credentials and findings sharply questioned. Curley Culp Jersey . With Pistorius now back watching the proceedings from a wooden bench, the double-amputee Olympians defence team was attempting to bolster his account that he shot girlfriend Reeva Steenkamp by mistake through a toilet door in his home, thinking she was a dangerous intruder about to attack him in the night. Pistorius faces 25 years to life in prison if convicted of premeditated murder in Steenkamps death in the early hours of Valentines Day last year. But former police officer Roger Dixon, testifying for the defence, also appeared unsteady as chief prosecutor Gerrie Nel warned him that it was irresponsible to "try and be an expert" in areas he was not. Nel asserted in his cross-examination that Dixon was not an expert in light, sound, ballistics, gunshot wounds or pathology -- all areas about which he was testifying. Dixon worked at the police forensic laboratory in Pretoria until he left the force in December 2012. He was a specialist in analyzing materials at crime scenes. He now works in the geology department at the University of Pretoria. Nel also accused him of not answering questions directly. "For an expert you are evasive," Nel said, prompting the judge at one point to tell the energetic prosecutor to "restrain" himself. Earlier, the judge ruled that proceedings will adjourn for more than two weeks after Thursday because a member of the prosecution team has another case to attend to. The trial will resume on May 5. During the cross-examination, Nel showed that Dixons findings regarding Steenkamps gunshot wounds came from analysis of autopsy photos and from a pathologists report because he was not present at the autopsy. He also hadnt read parts of the pathology report, Nel charged. The prosecutor also criticized Dixon for not bringing photographs and his written reports with him and abruptly told him to bring them on Thursday. "I said I will," Dixon snapped back. "Good," Nel responded. Nel ridiculed Dixons finding about the sequence of the shots that Pistorius fired at Steenkamp through the door, testimony which contradicted that of a police ballistics expert and state pathologist Prof. Gert Saayman. "I use the word finding very loosely," Nel said wryly of Dixons theory. Questioned by defence lawyer Barry Roux, Dixon said he believed Steenkamp was hit in the hip and the arm in quick succession by the first two of four shots while she was standing close to the toilet door. Raising his right arm in the courtroom, Dixon indicated he believed Steenkamp may have had her right arm extended and maybe her hand on the door handle, as if she was about to open the door through which she was shot. The defence was using his testimony to try to cast doubt on the prosecutions account that Steenkamp fled to the toilet and was hiding there during a fight with Pistorius. Nel has said that the runner intentionally shot Steenkamp through the door as she faced him and while they were arguing. Nel mocked what he said was a suggestion by Dixon that Steenkamp was knocked backward by one of the bullets. "Its something you see on TV," Nel said dismissively, challenging the expert to find scientific literature that showed it was possible. Nel also pounced on Dixons concession that an audio test that the defence conducted to compare the sounds of gunshots to those of a cricket bat hitting a wood door -- which both happened on the night of the killing -- had to be done a second time because of problems with the first. He even asked him if he was an expert at swinging a cricket bat, a cutting reference to his hitting a bat on a wood door in the defences audio tests at a gun range. Dixon had also said he took part in the audio tests that showed the sounds of gunshots and of a cricket bat hitting a wood door were similar and could be confused. That is important because several neighbours have testified that they heard Steenkamp scream before shots on the fatal night, backing the prosecutions case that there was a fight before Pistorius shot his girlfriend with his 9 mm pistol. Pistorius defence says the witnesses are mistaking the sequence and they heard Pistorius screaming in a high-pitched voice for help before breaking the toilet door open with his bat to get to Steenkamp. When played by Pistorius lawyers in courts, the two noises were similar. But questioned by Nel, Dixon said the tests had to be repeated and that they were recorded and edited by a music producer who had no experience in recording gunshots. "I have no idea on the expertise of the person who recorded the sounds," Dixon said. Marcus Allen Jersey . -- Albert Pujols is thrilled to have a reason to forget about his first two disappointing seasons with the Los Angeles Angels. Deron Cherry Jersey . "Back in 2011, when they announced that the game was coming here, we knew that it was going to be pretty important that we had a good year and hopefully could get into it, let alone win it, so I felt some pressure obviously within for sure," Taman said Monday, less than 24 hours after the Riders won the championship.Denver, CO (SportsNetwork.com) - Ty Lawson contributed 29 points and dished out 12 assists to lead the Denver Nuggets to a 114-107 win over the short- handed Dallas Mavericks on Wednesday night. Kenneth Faried totaled 22 points with 14 rebounds for the Nuggets, while Wilson Chandler posted 15 points, 10 rebounds and six assists in the win. Denver has won a season high-tying five straight. Dallas, playing in the second half of a back-to-back after nipping Sacramento in overtime on Tuesday, rested forwards Dirk Nowitzki and Tyson Chandler. Point guard Rajon Rondo also took the night off to rest a sore left Achilles. Our defense wasnt very good tonight, starting from the beginning of the game, Nuggets coach Brian Shaw said. Thats one thing I was worried about, with three of their starters out, our guys would relax a little bit. J.J. Barea had a team-high 17 points off the bench for the Mavs, while regular starters Chandler Parsons and Monta Ellis combined to score 18 points on 7- of-24 shooting. Ellis had just five points on 1-for-11 shooting as Dallas dropped the third game in its last four. All things considered we did a lot of good things tonight. But we had too many lapses and mistakes, Mavs coach Rick Carlisle said. Richard Jeffersons 3-pointer closed Dallas gap to 101-95 with 5:05 remaining in the fourth, then Devin Harris layup less than a minute later cut the margin to four. Lawson responded with a mid-range jumper, was fouled and hit the subsequent free throw to keep the Nuggets in front. Parsons then buried a jumper from just inside the arc, after he converted a layup, that made it a three-point game with over three minutes on the clock. Art Still Jersey. Faried came up with a big offensive rebound inside two minutes and knocked down two free throws. Lawson found Faried inside for a layup on the next Nuggets possession and they held on down the stretch. We were able to still get the win and we understand that we are going to have to play better, Shaw added. Denver made half of its shots in the opening quarter and limited the Mavs to 1-of-7 shooting from beyond the arc, taking a 28-24 lead into the second. The Nuggets continued their hot shooting in the second quarter and again held Dallas to just 1-of-7 shooting from 3-point range. J.J. Hicksons three-point play gave the hosts a double-digit lead just before half and Denver held a 59-50 lead at the break. Parsons trey early in the third cut the Mavs deficit to 61-55, but Denver followed with 13 straight points. Dallas went 4:12 without a score during the run as the Nuggets gained comfortable control. Barea then fueled a 12-1 run with seven points to help the Mavs work their way back to 79-71. Alonzo Gees 3-pointer pushed the margin back to 15, but Charlie Villanueva canned a triple just before the buzzer to pull the visitors within 90-78 entering the fourth.
