SAN DIEGO—A woman who was stabbed to death at Central Avenue Mini Park in City Heights was identified on June 22 as a 65-year-old San Diego resident.

ChiThiKim Cao, a Vietnamese woman, was identified as the stabbing victim, according to Lt. Steve Shebloski of the San Diego Police Department (SDPD).

On Monday, police arrested Siliveinusi Patafalai Hamala, 23, at his residence in the 3000 block of 39th Street and booked him into the San Diego County Jail on suspicion of murder, Shebloski said.

Cao was exercising at the mini park when Hamala allegedly attacked her shortly before 8:30 a.m., according the lieutenant.

“Unfortunately, despite the best efforts of officers and medical personnel, the female suffered catastrophic injuries and was pronounced deceased at the scene,” a June 22 press release from the department stated.

It was unclear what motivated the deadly violence, which apparently erupted without provocation or warning, according to police.

“There is no indication there was an altercation before the [woman] was attacked or that she was targeted for a specific reason,” Shebloski said.

Anyone with additional information about this stabbing was asked to call the SDPD Homicide Unit at 619-531-2293. Anonymous callers can contact San Diego County Crime Stoppers at 888-580-8477 or contact the agency online here. Tipsters can remain anonymous and could be eligible for a reward of up to $1,000.
