We have measured the line-of-sight velocity profiles of M32. The major
axis velocity profiles are asymmetric, with opposite asymmetry on
opposite sides of the nucleus. Existing models for M32 cannot account
for these asymmetries. We present new models which assume the
distribution function to be of the form f=f(E,L_z). Such models
require a central black hole of approximately 1.8 x 10^6 solar masses
to fit the observed rotation velocities and velocity
dispersions. Without invoking any further free parameters, these
models provide a good fit to the observed velocity profile
