Houston police have charged 18-year-old Jefferson Velasquez with murder in a Midtown shooting, and he was already in the Harris County Jail facing a separate murder charge from a house party in East Harris County.

Records show both deadly shootings happened under similar circumstances involving large gatherings, and according to records, Velasquez has a pattern of allegedly robbing people of their chains at large parties.

Velasquez is scheduled to appear in court Thursday morning on the new murder charge.
