SAN DIEGO (Border Report) — The head of the Border Patrol’s San Diego Sector says her agents encountered 9,513 migrant apprehensions from April 17-23.

Chief Patrol Agent Patricia McGurk-Daniel last Thursday took to X to share the numbers, which agency officials say make it the busiest sector along the southern border this month.

A local official has also labeled the region as the “epicenter for illegal immigration.”

In a statement late last week, San Diego County Supervisor Jim Desmond said that the number of apprehensions in the San Diego Sector has “propelled San Diego to the unfortunate position of leading all nine southern border sectors in April, a trend unseen since the 1990s.”

Border Patrol has confirmed that so far in April, San Diego has had more apprehensions than any other sector.

Volunteers who feed and hand out water to migrants in an area by Border Patrol agents call “Whiskey 8,” say they too have seen an increase in migrant crossings in recent weeks.

They told Border Report on Monday that they saw upwards of 300 migrants during mornings last week.

On Monday morning, they reported helping two groups of asylum-seekers totaling 60 before agents took the migrants to Border Patrol stations for processing.

The official numbers for the month of April won’t be made public until mid-May.

The most up-to-date figures show that in the San Diego Sector, since October 1 when the current fiscal year began, 185,469 migrants had been apprehended through the end of March, compared to 342,002 in the Tucson Sector.

Last month, San Diego Sector had 33,784 apprehensions, Tucson 41,941 and El Paso had 30,420.
