Mexican authorities say two professional wrestlers found dead in a low-rent hotel in the capital may have been drugged to death by female robbers.

Autopsies are being performed on the two midget wrestlers, one of whom went by the name "La Parkita" — or "Little Death" — and wore a skeleton costume in the ring. The other was known as "Espectrito Jr."

Authorities say two women were seen leaving the men's hotel room before the bodies were discovered.

Prosecutor Miguel Angel Mancera said Wednesday that gangs of female robbers are experienced at using drugs to knock men out and rob them, but they may have used too strong a dose.

That may have been because of the wrestlers' small stature, although larger men have also died in similar crimes.
