My daughter was interrogated very hardly & to the point that she said forget it....then they told her it was a felony & she could go to jail..?

My daughter pulled her car over & opened door to get air as she felt sick. Was approached by a man trying to take her car. She fought..screamed...got him with box cutter & he ran off. She drove home...was scratched all over bleeding....and so upset she couldn't talk. I talked her into filing police report...after a week they called her in and interrogated her for an hour...upsetting her so badly. Told her she made it up & could go to jail for false report however since she recently lost her twin babies & went thru a hard time he could use mental health as reasoning & she would probably just get probation & need to seek professional help which she needed anyways after going thru this! He said she would be served a supeona to appear in court. The way she was treated was terrible & no need. She is scared to death she will go to jail now....advice?
