My mom killed herself

I got a call at 1a.m this morning. My sister (Chrystal) was crying. She asked if mom was here. She wasn't. So naturally I asked what was going on. Mom had left at 7pm, told chrystal she could have the house, said she had nothing to live for anymore, and said she was going kill herself. My uncle's went look for her. They can't find her. The police wont help until 48 hrs. after she went missing. I love my mom, she be evil... but if she is dead because we were too late, i will kill the gray police force!
