A Southmost father remains in custody under $1 million dollar bond after being charged for the death of his 1-month-old son.
Brownsville police arrested 17-year-old Israel Avila under a capital murder charge late Monday.
Investigators told Action 4 News that 1-month-old Marcos Avila was admitted to the Valley Regional Medical Center with bruising around 10 a.m. Monday.
Detective had already started investigating the case when Baby Marcos died from his injuries.
Police told Action 4 News that Avila admitted to beating the baby boy because he was crying.
