Tenant stopped paying rent after March 31, 2020, refused to pay or leave property.

Tenant had a lease that ended Dec. 31, 2019, asked to extend month to month saying they expected to move End of March 2020. Allowed tenant to remain and pay each month. Tenant did not communicate move date, did not call or contact to communicate they were not going to pay April. Contacted tenant to collect April rent, tenant refused to pay. Covid eviction moratorium had started, advised they had to pay rent or move by end of April. Tenant said they would live out last month and security (2 months.) Advised these were not to live out as stated in lease. Tenants has not communicated nor contacted landlord after landlord’s repeated calls and letters to tenants. Letters sent next day hand delivry, and communication left on door and no response from tenant. Both security and last month deposits applied April & May. June and July rent not paid rent not paid. Tenant has refused to vacate property, still no response to any landlord communication. What to do, how can this tenant be removed???
