We use near-infrared photometry and astrometry from the VISTA Variables inthe Via Lactea (VVV) survey to analyse microlensing events containing annualmicrolensing parallax information. These events are located in highly extinctedand low-latitude regions of the Galactic bulge typically off-limits to opticalmicrolensing surveys. We fit a catalog of $1959$ events previously found in theVVV and extract $21$ microlensing parallax candidates. The fitting is doneusing nested sampling to automatically characterise the multi-modal anddegenerate posterior distributions of the annual microlensing parallax signal.We compute the probability density in lens mass-distance using the sourceproper motion and a Galactic model of disc and bulge deflectors. By comparingthe expected flux from a main sequence lens to the baseline magnitude andblending parameter, we identify 4 candidates which have probability $> 50$%that the lens is dark. The strongest candidate corresponds to a nearby($\approx0.78$ kpc), medium-mass ($1.46^{+1.13}_{-0.71} \ M_{\odot}$) darkremnant as lens. In the next strongest, the lens is located at heliocentricdistance $\approx5.3$ kpc. It is a dark remnant with a mass of$1.63^{+1.15}_{-0.70} \ M_{\odot}$. Both of those candidates are most likelyneutron stars, though possibly high-mass white dwarfs. The last two events mayalso be caused by dark remnants, though we are unable to rule out otherpossibilities because of limitations in the data.
