What to Know
Castillo he had a relationship with Kristin White after separating from his wife. They broke up, but he called and wrote White from jail.
The prosecution questioned Castillo's alibi, namely the black eye he received the night she died and his trip to his friend's house.
A jury heard closing arguments Friday in the murder trial for a Loudoun County man accused of killing his estranged wife and trying to make her death look like a suicide.
Braulio Castillo is accused of killing his wife, Michelle, in 2014. The two were in the middle of a bitter divorce and custody battle.
The defense says Michelle took her own life, but Friday, prosecutors told the jury that Michelle Castillo was happy and had just qualified for the Boston Marathon, arguing she had no reason to commit suicide.
The prosecution also claimed that Braulio Castillo tried to smother his wife with a pillow as she slept, but stopped when he realized his young son was also in the bed. He told the boy to go to another room before allegedly committing the crime.
In May, two of Castillo's children testified in court. Eight-year-old Zack Castillo said he saw his father the night before he woke up to find his mom missing. He said he initially was sleeping in his mom’s bed until she told him to move. He then went to sleep with his older brother Jonathan but left his special blanket behind. He testified he saw his dad bring the blanket into his brother’s room during the night.
Jonathan Castillo, 11, testified his father asked if there was a security camera. He also testified his father asked for the alarm system numbers in exchange for a gold coin.
The oldest son, 23-year-old Nicholas Castillo, testified against his father on June 6 and said he recognized a man seen in a neighbor's security camera video the night of his mother's death as his father.
During closing arguments Friday, the prosecutor urged jurors to think about the protective order Michelle had against Braulio.
"According to two courts, she and her children needed safety," the prosecutor said.
She read the definition of family abuse as "any act involving violence, force, or threat."
"That's Braulio Castillo, that's the truth of what this marriage was," she said. "This was an abusive man. This was an abused woman."
But defense attorney for Braulio Castillo said that although Michelle had a protective order against her husband, it didn't say there was "assaultive behavior."
The attorney also brought up a security camera video that shows someone running around and into the Castillo house, saying there was no evidence who was in the video and "there is no credible evidence that is Braulio Castillo running across the house." He argued there was no evidence that Braulio had the security code to get into his wife's house.
The defense attorney also questioned why Braulio would kill Michelle in her own house, where her children were sleeping, asking why he wouldn't have done it on the W&OD trail while she was running early one morning. "Use your common sense," he said.
The attorney showed jurors a picture of the family, asking them, "Do you think that he would take from those happy people?" He asked, "Does that make sense that he was so filled with hate... although there's no evidence of it... that he removed those kids from their mother?"
The attorney discussed the likelihood Michelle took her own life, saying their housekeeper testified that in the days leading to her death, Michelle was "increasingly sad." He said her doctor testified that she had anxiety and that she was emotional, and showed texts to friends reading that she "feels like a failure" and that she was "disgusted" with herself.
