Residents of a Marmion Avenue building say security has been shored up following a homicide last week.

The building?s tenants say the lackluster security at 1971 Marmion Ave. left the building vulnerable to a shooting in which a man ? who tenants say did not live in the apartment complex - was shot and killed Jan. 16.

The building?s management company installed locks at the building?s front gate to keep trespassers out. Tenants say they have also asked that surveillance cameras be installed.
