<human>: About three weeks ago my mom's car started smelling like gas. We got her car towed to the shop and they said the fuel line was leaking. Thought nothing of it, shit happens, got it fixed. Today my mom woke up and went out to her car to the smell of gas again. Looked under the car and the fuel line was leaking again. Thought this is bullshit. Call a tow truck to get it taken to the shop and this time they called my mom.

"Fuel lines do not fail this often. I've been dealing with cars a long time and this line has been cut. This is not an animal or an accident someone deliberately cut your fuel line." 

The shop took pictures and we called the police. They are going to come out and investigate on Saturday but I'm scared in the mean time.

My mom last drove the car on Saturday which means that it had to have happened between Saturday night around 10PM and this morning at about 12:00 Noon. I have driven my car, which is parked right near hers, since then and I did not see or smell any gas coming from the car. So either I didn't notice or it happened last night or this morning. This is the first time anything like this has happened and I'm not sure to go about it. The police said be extremely careful but there isn't a whole lot they can do without any picture or evidence and suggest setting up a camera. I'm not sure what kind of camera to get or anything and I would really like to do something to help stop this as I'm scared for my mothers life.

Could you distill the essence of the text into 1-3 sentences?
