There are a few sentences I can't make sense of. Can you please help me. Thank you very much in advance.

1) Together with interviewing witnesses their job (the job of forensic artists) shouldn't be so long and the criminal could be discovered fast.
2) This method of solving crimes has helped to solve a lot of crimes because the forensic artist was so accurate that they (he) could find the criminal easily. (being so accurate this method has helped forensic artists to catch thousands of criminals).
3) I was just coming back home when I heard someone walking behind me. At first, I didn’t care since it could be anyone. Then his steps became louder. My purse was on my right shoulder so I pressed it against my body.
4) Then I felt it being pulled and I tried to pull it back. That was when I saw his face. Brown eyes, big nose, small ears and large (?) eyebrows.
5)He was red-haired and hsi teeth were yellow. One was a golden tooth. He was wearing a light pair of jeans and a yellow T-shirt. He also had a beard and it was long. That’s all I can remember.
5) Forensic artists must have other two skills. First, they must have good interview skills and second, they have to remember the victims important details about the crime, such as scars or hairstyles.

1) The job of forensic artists includes interviewing witnesses, but their job shouldn't take too long so the criminal could be discovered fast.

I'm not sure I figured out what this means. Is it quoted from someplace else?

2) Using forensic artists to solve crimes has helped to solve many because the artists have been so accurate that law enforcement officers could find the criminals easily.
???

3) I was just coming back home when I heard someone walking behind me. At first, I didn’t care since it could be anyone. Then his steps became louder. My purse was on my right shoulder so I pressed it against my body.
This is fine.

4) Then I felt my purse being yanked away from me, and I tried to pull it back. That was when I saw his face: He had brown eyes, a big nose, small ears and thick, bushy eyebrows.

5)He was red-haired and his teeth were yellow. One was a golden tooth. He was wearing a light-blue pair of jeans and a yellow T-shirt. He also had a long beard. That’s all I can remember.


6) Forensic artists must have two other skills. First, they must have good interview skills, and second, they have to remember the victim's important details about the crime, such as scars or hairstyles.

Be sure to compare yours and mine VERY carefully to catch all the large and small corrections I made.

Now ... do you need explanations or has fixing the sentences helped?
