An 18-year-old male was killed and a 19-year-old was critically injured in a shooting Monday afternoon inside a house on Sunnyside Lane.

Lafayette police spokesman Cpl. Paul Mouton said five people were inside the home at 318 Sunnyside Lane off Pinhook when two men drove up in a red pickup truck, walked into the home and began firing at 4:10 p.m.

The shooters fled before police arrived, Mouton said. The other three people inside the house, two men and one woman, are unharmed.

The injured 19-year-old was transported to a hospital in critical condition, Mouton said.

The motive for the shootings remained unknown Monday afternoon, he said.

Detectives are asking anyone with information about the homicide to call Lafayette Police or Crime Stoppers at (337) 232-TIPS.
