Sorry for abusing the brilliance of Story Research 
. Two circumstances where the police get involved, and I need to know how closely the police would be watching my main character, and how much she can believably do. Important note: she's the daughter of a cop, but daddy's famously blinkered when it comes to her (the other cops notice).
1) Sixteen-year-old lead characters gets beaten up and stabbed outside a party under suspicious circumstances. There are no witnesses because she was actually stabbed by a serial killer who set her up, and nobody's reliable because it was a standard Wild Teen Party. He's blackmailing her with something he learns about her so she has to protect him to the police (this makes sense in-story, I promise). The police obviously figure out that she's hiding something as she claims very convenient memory loss, and as the alcohol and drugs are on the premises, almost everyone's memory of the night is impaired and those who sort-of remember act shifty. When she gets discharged from hospital, how long would she be watched by the police? How closely, and how long would she have to worry about the investigation if it appeared totally stagnant?
2) Lead character's friend disappears, thanks to her friendly serial killer. When she finds out, the main character goes to her friend's house, knowing it will be empty, and steals clothes from her (making it look like she ran away), which she hides. She then pretends to have gone to the house and looked for her friend, and found that the clothes are missing. How long would she be watched by the police? Could she leave to see someone without being monitored/supervised within ~24 hours ish?
