helin's father has called for stricter gun laws.ihat: i want to see at least the many illegal arms confiscated. that would save many lives, because many of these firearms are owned by uneducated people who have a sick mentality. reporter: nihat doesn't need to long to find the spot where his daughter was killed -- it looks like a war zone. the culprit fired repeatedly on his daughter with a semi-automatic rifle. he was later apprehended. the man who illegally sold him the gun, however, was quickly released. nihat: i or anyone else could end up being shot soon, too. this has to stop. i don't want others having to live though what i have endured. i lost my child. enough. reporter: there are now fatal shootings on the streets of turkey every day. helin's former school friends were shocked by her death. but they know how easy it is to buy a gun these days. >> it's simple. you order a firearm online, and it's delivered to your doorstep. incredible, really. reporter: it's illegal to buy arms online in turkey. but that does little to allay
