Casement Window Security

A quick learner from Las Vegas, NV says:
Recently my parent's house was burglarized. They gained entry through a casement window that was mounted fairly low to the ground. It appears the window pane that normally opens was pried away from the frame enough to then pull it away resulting in the gears inside the crank breaking.

I've looked at locks that can be added to the frame but there is not a lot of room to add one and I'm afraid of cracking the glass while drilling holes to mount a lock. I currently have plastic zip ties holding down the locking handle. Is there another way to add a secondary lock? It is a Fentron crank handle. Thank you.

Do you have a lock installed on this window originally? Viewing this window from the inside, there should be one on the right side of the window. If so, I'd like to have a look at it. If not, is there a hole where one once was installed, maybe one that has since been covered up?

Here is a picture I took recently of the original window lock that I have since secured with two zip ties. I did this since the latch did not fit tight when in the down position. This picture shows the screen installed while the first picture shows it missing. I think the bad guys were able to jiggle the window frame from the outside which caused the handle to come loose. Just a theory since I wasn't there at the time.

Thank you! I would start with looking at our 38-001 or 38-005. I think one of these could be a match, depending on what the locking hook looks like on your own part.

Thank you both for your help. I just ordered a new operator and locking handle from your company to replace the old window parts.
