Why did this happen and how can parents better protect their kids . We have some details now about the 15yearold suspect thought to be a trusted neighbor of maddy. Nbc bay areas Chuck Coppola is at the apartment complex in santa cruz with more. Chuck. Reporter raj, the boyfriend of the victims mother told me that the teen arrested was like a mentor to younger children here at the apartment complex, and there are a lot of them here. Some 50 kids live with their families here. You can see perhaps that is one reason why the memorial to maddy has grown so much in just one day. As parents now try to process that at least according to police the threat apparently came from within. Laura al brecht brought her children to the growing memorial for maddy today. She tried to figure out how to talk to her own children about staying safe. We have to teach them how to protect themselves too. And how to be aware of possible dangerous situations and talk to them about not going into other peoples houses. Reporter but tough questions remain. How do parents in this selfdescribed tightly knit artists colony convince their children there is no threat here . That is the really big issue for us moving forward. Is the issue of trust. I mean we have about 50 kids on this property. They all know each other. They all play with each other. They all hang out at house dates with each other. So there is a lot of like in any community, a lot of interaction between everybody. So now moving forward, that whole theres a trust breach here. Reporter kirby, the boy friend of the victims mother knows the 15yearold boy arrested. For the last six years, hes been here Everybody Knows him, everybody has interacted with him. Hes incredibly great kid. And this is a tragedy for him and for his family.

Well have the story, coming up next. Were not competing with each other. Were just really competing with ourselves. Its never been done before. The Epic Challenge two bay area swimmers are about to take on. Its part of our bay area proud series. Then at 6 00 are you ready for an army of delivery drones flying right above your head . The super highway of drones that amazon wants to create. Thats new at 6 00. A disturbing sight to see during the drought. Millions of gallons of Drinking Water wasted ate a disturbing sight to see during the drought. Millions of gallons of Drinking Water wasted after a pipe burst on the peninsula. It happened at the san bruno entrance. Water flowed all night and half the morning today. Nbc bay areas Mark Matthews is there live. And mark the big question why did it take so long to shut the water off . Reporter ill tell you, the pipe theyre working on is a big one, four and a half feet in diameter. Come on in. The hole is at the bottom of this pipe. And im told that if they had shut the water off, meaning cities many cities on the peninsula would have woken up this morning without any water at all. Rather than turn the water off, San Franciscos Public Utilities commission decided to keep the line pressurized, and the water flowing, even though a huge amount was washing down the hill and into a storm drain. I had to guess, it would be 15 million gallons. Reporter thats onefifth of the daily water use for San Francisco and much of the peninsula. If they had cut the water off on this broken main daly city san bruno, pacifica and the San Francisco jail would have been dry. So they kept the line pressurized for hours. Long enough to allow the wholesale customers to reconfigure their systems so that all the retail customers stay in clean water. Reporter the break in this pipe was caused by rust. The pipe was installed in the late 1920s, and a spokesman for the puc says theres 320 miles of old pipe that they are replacing at a rate of 15 miles per year. We have a very old system that we want to continue replacing more and more. And until we get to that point where we are in the state of good repair, youre going to see water main breaks. And thats part of running a water system. Reporter but in a drought, its particularly tough to watch so much water going to waste. In san bruno, Mark Matthews nbc bay area news. We all have that reaction. No, get that water back. We can use it for our yards and everything else. Lets bring in chief meteorologist jeff ranieri now. Jeff, it is hot. It definitely is. One of those days where you head to get in your car and crank the ac up but you can still feel it for several minutes as temperatures surpassed 100 degrees for a good section of our interior valleys. Right now, still averaging well above average in the south bay with 97 degrees. Peninsula, 86. San francisco was in the 80s today and you could see across the north bay, 96. No doubt the hottest widespread weather is right here across the east bay. So lets get a check of those microclimates right now. And you can see the warmest weather is right throughout this corridor of pittsburg, antioch, north brentwood, all coming in with 105 degrees. Lafayette, 99. Orinda 95 and right down the corridor from danville to pleasanton, temperatures generally ranging in the low 100s. So with this heat in place, i do think well see some cooling for tomorrow morning, a little bit of recovery. But its going to start mild and the temperatures are going to warm up fast. Lets go ahead and take a look and you can see as we start off wednesday morning, well begin with 66 in the south bay. 69 for the east bay, and for the north bay, starting off with 62 degrees. So not a bad morning, mainly clear skies. But then as we head throughout the day, were anticipating 1 to 2 degrees of an increase in those temperatures. Thats going to put downtown san jose at 99 degrees for the high. Dangerous levels of heat again in morgan hills. So you want to make sure to drink plenty of water if you work outside, try and limit your outdoor exposure if its possible. Take some breaks indoors. Youll see for the peninsula, pretty nice in pacifica 77 with beach weather. And palo alto, 96. And San Francisco, near the Golden Gate Bridge a slight wind off the bay will put your temperature at 77. But if you head to the interior peninsula, back towards the mission or also the financial district, temperatures in the low 80s. Lets get you up to the north bay, east bay and also for the tri valley and, yes, you notice a lot of low 100s here. Napa and also santa rosa. The kind of weather where, again, you cannot forget that water, 102 degrees up in the vineyards and Napa Santa Rosa 100. For the east bay, you have 86 in oakland, but you come out the called cot tunnel the thermometer in the car shoots up to 103 degrees. And the worst heat will be throughout the tri valley. 105 in pleasanton. Also 103 in danville. So whats producing the heat . Nothing too out of the ordinary in terms of the pattern. Its High Pressure thats just unusually strong. That stays in place, and it looks like at least for the next two days in the forecast. So as youre going to be able to see in our temperature trend here all the way through thursday, hot weather remaining in place. Then by friday we get some cooling. Now that cooling in the forecast, thats going to be coming from this storm system were tracking off shore by friday. And upper level low pressure system. It will push in some monsoonal moisture and may actually bring in some isolated thunderstorms here to the bay area. So lets go ahead and take a look at the extended forecast and what youre going to be able to find as we head throughout saturday and also sunday temperatures definitely not going to be hot here. 86 for the south bay on saturday. 84 by sunday. So again, very hot weather for tomorrow. And then we cool off this upcoming weekend. Ooh, okay. Thank you, jeff.
