A woman who fell to her death at Petco Park while holding her toddler son last September died by suicide, according to the San Diego Police Department.

Authorities ruled her 2-year-old son's death a homicide.

Raquel Wilkins, 40, and her son, Denzel Browning-Wilkins, fell around 3:50 p.m. on Sept. 25 as baseball fans were heading into the stadium for a San Diego Padres game against the Atlanta Braves.

Wednesday's statement said detectives "conducted a thorough and comprehensive investigation that included dozens of interviews, reviewing of available video footage, and collecting background information to determine what led to the deaths."

It said the decision was made in consultation with the San Diego County Medical Examiner.
