SACRAMENTO, Calif. -- Two stabbings that happened in 2006 may be linked to the recent serial stabbings along Del Paso Boulevard, police said Thursday.

Both of the '06 stabbings happened within the same area as the recent series, but the connection is not definitive and there are major differences from the latest attacks, police said.

All of the recent stabbings appear to be random and have taken place near Del Paso Boulevard between Arden Way and El Camino Avenue, officials said.

On June 28, 2006, Robert Wright was riding his bicycle home from church on Eleanor Avenue when he was approached by a man who stabbed him in the back. The man who committed the stabbing was never found, police said.

Wright, who was 64 when he was attacked, died on Feb. 5, 2008.

A coroner who performed an autopsy on Wright's body concluded that he died as a result of the stabbing.

On Aug. 21, 2006, David Loucks was walking in the area of Del Paso Boulevard and Glenrose Avenue when he was approached by a man on foot. The man allegedly said "good evening" to Loucks and then stabbed him in the back.

Loucks, who was 69 when he was attacked, recovered from his injuries.

In the recent assaults, the assailant has never said anything or attempted to rob his victims, officials said, and in each attack he has been riding a bicycle while his victims have been on foot.

Police said they are looking for a Hispanic man, about 22 to 28 years old, 5 foot 7 inches to 5 foot 10 inches tall and weighing 170 pounds.

The man's bike has been described by police as a 10-speed or mountain bike that is possibly red, gray or tan.

The knife involved in the stabbings is about 6 inches in length, with a black handle and may be a Swiss Army knife, officials said.

Anyone with information on this case can call Crime Alert at 916-443-HELP. Callers can remain anonymous and may be eligible for a reward up to $1,000.
