The 31-year-old suspect who fatally chopped mother of two Reshma Kanchan is said to be recovering from his injuries.
After the suspect chopped his estranged wife, he slit his throat in an attempt to kill himself.
But he was found at the scene of the crime and taken to the San Fernando General Hospital, where he is currently warded in serious but stable condition.
Police expect him to make a full recovery, following which they will question him about the incident.
Kanchan was on her way to work last Tuesday morning when the suspect attacked her, severely chopping her several times about her head.
She was buried on Saturday.
