This emerged yesterday in the Pretoria Magistrate's Court when prosecutor Gerrie Nel re-examined investigating officer Petrus van der Spuy in Gouws's bail application.
Van der Spuy told the court that the curator appointed on behalf of Henning's son had written in a report for the high court that: "He [Gouws] said he followed the deceased months prior to the murder, monitoring her interaction with male friends."
Gouws apparently did this while Henning was in the process of divorcing Nico - his close friend. Gouws told the curator he had followed Henning on his own initiative.
Henning was gunned down after dropping her son off at a preschool in Faerie Glen, east of Pretoria, on November 8. A custody battle was pending and the child was placed in foster care.
Gouws, a former policeman, was arrested together with former Nigerian Olympic athlete Ambrose Monye, Gerhardus du Plessis, Willem Pieterse and Preshan Singh.
Pieterse and Du Plessis admitted to the murder. Singh, who provided the murder weapon, was released on R5000 bail in November. Monye allegedly ordered the hit and Gouws allegedly pointed out where the mother lived and worked, and the child's school.
Francois Moller, a cellphone forensic analyst for the Hawks, testified that manycalls were made between Gouws, Pieterse and Monye between October 1 and November 11. He said Gouws sent two SMSes to Nico Henning the day before his wife's murder and that Gouws had tried to phone and SMS Nico on the day of the murder but he could not get through because Nico's cellphone had been stolen.
Moller said all records of calls between Gouws, and Nico and Monye, had been deleted. Monye called Gouws 55 times, Monye 26 times. Numerous calls were made between Gouws and Pieterse.
"Cellphone towers show that Gouws and Pieterse were in the area [Faerie Glen] days before the murder," he said.
The application continues.
