>> announcer: from nbc news world headquarters in new york, this is nbc nightly news with lester hold holt. >> good evening. it's more than 24 hours since a jury of women was sent behind closed doors to decide a murder trial that riveted this country for the last several weeks. the shooting death by a neighborhood watch volunteer in sanford, florida. tonight still no verdict. the suspension this this emotionally charged case is building inside and outside the courthouse and so are tensions. the requesty to be answered, whether george zimmerman shot and killed trayvon martin in an act of self defense. the prosecution contents it was second-degree murder. we will get legal perspective, but ron mott is outside the courthouse where there have been late developments. what's happening now? >> reporter: good evening to you. this jury has been almost three weeks and deliberating for 13 hours and counting and they asked the court to clarify the instruction for manslaughter. >> your verdict finding george zimmerman either guilty or not guilty must be unanimous. >> after 56 witnesses, 12 days of testimony and an assortment of evidence to digest, a chunk of concrete. >> on the sidewalk. >> a dummy. >> george zimmerman and trayvon martin. >> six women continue to tlib rate and among them five managers. the options. guiltiy of second-degree murder, guilty of manslaughter or not guilty. it will hinge on how they resolve key issues. who cried out for help? >> trayvon berchl min martin. >> my son, george. >> the position of the hol ter. >> he is saying that arm pits, how does he get the gun out? are. >> how severe were the judge ares? his description of trayvon martin in a call to police. >> so much of this case is documentary evidence. it's either a video, audio tape or photograph. jurors like that and prefer that rather than witness testimony or recollections. >> throughout the trial, defense attorneys did not stray often or far from their central argument that zimmerman fired in self defense after being attacked. he pleaded not guilt tow second-degree murder. >> i almost wish the verdict had guilty, not guilty and completely innocent. because i would ask you to check that one. >> by contrast, prosecutors sought to expose what they called inconsistencies or lies in zimmerman's accounts of the event. >> i submit to you trayvon benjamin martin is titled to the choice. it didn't come from his mouth. he told so many lies. that's why we are here. >> the jury heard a range of witnesses from the woman on the phone with martin during the encounter. >> i heard trayvon saying get off, get off. >> the lead investigator. of the first to interview him. >> you say following is not legally proper some are. >> it's not illegal. >> many thought they would come back quickly. that has not happened. we are past the point where they say it was a quick decision. >> they have gathered outside the courtroom all day. they have been larmly peaceful, but at one point there was a shouting match this required deputies to step in. there have been no injuries or arrests. >> i want to bring in legal analyst and veteran attorney kendall coffee. you heard the jury is asking for clarification on manslaughter. keeping in mind the prosecution is going for second-degree murder. what's the significance some are. >> both are subject to self defense. manslaughter is easier to prove. it doesn't require even an actual intent to cause the death of trayvon martin and doesn't require the hatred or spite that a second-degree murder charge would require. in order if manslaughter is returned as a conviction, the consequences are very serious. up to 30-year maximum prison time. >> trial watchers couldn't begin to speculate when they heard the request. is there anything we can read into that they want to hear more about manslaughter? are. >> we never know what the jury is thinking, but it suggests they are giving consideration to a charge of manslaughter. given everything that happened in the trial, that's a positive for the prosecution rather than a quick acquittal. they are thinking about manslaughter. that's a fascinating and intriguing development. >> kendall coffee, thanks if are being with us. in texas, high dramaa late into the night and in the end republicans have tough new abortion restrictions, one of the strictest in the country. the texas governor

doctors to have admitting privileges within 30 miles of a clinic and require clinics to upgrade centers and say it would improve women's health. >> for their voices to be heard. >> critics led by senator wendy davis who defeated with a filibuster say the measure would force the abortion clinics to close. >> force more texas women to make dangerous, sometimes deadly decisions. >> the proceedings were disruptive times by protesters and chained herself to the brass railing. the vote was delayed until troopers could cut her loose. when it came, the vote was 19-11, mostly along party lines. >> we will push it to the point where abortion is called what it really is. the murder of a chile child. >> the next step i'm sure will occur outside the legislative process that will occur in the judicial system. >> courts blocked 20-week bans in arizona, georgia and idaho. new clinic registrations have been stalled in al bam and mississippi. the texas law might be tied up for years, but
