Penang's first recorded triple murder?

Is this possibly the first documented case of a murder (or multiple murders) in Penang? Maybe not, because I'm sure early Penang had its fair share of lawlessness in the early years after it became a British settlement. But according to a report in the Hampshire Telegraph & Portsmouth Gazette published on 13 Sep 1802, this was a notorious triple murder on the island:

A letter from Pelo Penang of the 23rd January, mentions the following murder to have been perpetrated there on the 12th preceding:- A Malay woman, her husband, and three other Malays, laid a plan to plunder the house of the late Peter Robertson, where there was only his daughter, a fine girl of ten years old, her mother, and a servant girl; to effect their wicked purposes, they made intoxicating cakes, and gave them to the people of the house to eat; after which they most inhumanly strangled the little girl, cut the throat of the mother, and stabbed the servant girl; the assassins then carried off the effects. They afterwards returned and set the house on fire; on the alarm of fire being given, several persons ran to the house, to see if the people in it were asleep, and to give them assistance; but as no answer was given from within, concluded they were not at home; after the house was burnt down, the three bodies were found, which gave immediate suspicion that they had been murdered; and by the activity of Mr Brown, the Provost, the murderers were found and have since confessed the enormous fact.
