TW possibly (dead) bedbugs? But I‘ve been told otherwise (see comment)

Hi, this is in Barcelona, Spain.

It’s in my mother’s house, she had been away at least 3 weeks when I noticed bites on me (very close together). These all seem dead and the ones on the bed sheets have been cleaned at 60 degree celsius. They were also on a bed that my mom only occasionally uses to read. Several exterminators have given her contradictory information based on the pictures and she can be a bit cryptic/ hard to communicate online. Any advice on identification would be very helpful.

I suspected bedbugs because I had them over 2 years ago and the bites were very similar (itched a bit but specially when scratched, not too far apart)
