In early 1590 Antonio Pérez was questioned under torture but he only confessed very vaguely implying the king was behind the killing. At this point he believed he may be sentenced to die and so, again, he planned his escape. On 19 April, with the help of his wife, Juana Coello, who was eight months pregnant, in the evening, he escaped his prison in Madrid. The escape was very carefully planned. With two loyal men he rode all night trying to gain the border of Aragon, separate kingdom with laws that protected him. In spite of his age and his poor physical state after being tortured, they rode all night changing horses along the Royal Posts. A second group followed a short while later, disguised as servants of a nobleman, with the purpose of tiring the Posts' horses and thus make them unavailable should any officers of the king try to follow.
